Correct Answer: A very strong letter has been written by me to the local administration regarding the deteriorating law and order situation.

Solution : The second option is the correct answer.

The passive voice is a grammatical construction where the subject of the sentence receives the action rather than performing it.

The structure of passive voice sentences follows: "Object of the active sentence + "to be" verb (in the appropriate tense) + past participle of the main verb + by + subject of the active sentence (optional) + rest of the sentence."

Therefore, the correct answer is: A very strong letter has been written by me to the local administration regarding the deteriorating law and order situation.

Correct Answer: Father

Solution : As per the given information, the family tree will be as follows –

Here, the quadrilateral represents the male, and the circular figure represents the female in the figure.

So, D is the father of F. Hence, the second option is correct.

Correct Answer: Running and jumping

Solution : (A) Running and jumping
"For every action there is an equal and opposite reaction". When one body exerts a force on a second the second body exerts a reaction force that is equal in magnitude and opposite in direction on the first body.

Correct Answer: Attorney-General

Solution : The correct answer is Attorney-General

The first law officer in India is the Attorney General for India. The Attorney General is the chief legal advisor to the Government of India and is appointed by the President of India. The Attorney General represents the government in legal matters and provides legal advice to various ministries and government departments.

Correct Answer: every

Solution : The correct choice is the second option.

Explanation: In the context of a representative democracy, the emphasis is on each individual vote having equal weight. The word "every" is more suitable for conveying the idea that every single vote is treated equally in terms of significance.

So, the correct answer is every.

Correct Answer: Y is the daughter of U

Solution : Given:
A & B⇒A is the sister of B.
A % B⇒A is the brother of B.
A * B⇒A is the mother of B.
A # B⇒A is the wife of B.

As per the given information, the family tree will be as follows –

Here, the quadrilateral represents the male and the circular figure represents the female in the figure.
Let's check each option –
First option: D is the mother–in–law of K→True
Second option: Q is the sister of D→True
Third option: Y is the daughter of U→False, as Y is the son of U.
Fourth option: U is the mother of D→True

Hence, the third option is correct.

Correct Answer: The marginal utility derived from the good decreases at a decreasing rate.

Solution : The correct answer is (d) The marginal utility derived from the good decreases at a decreasing rate.

According to the law of diminishing marginal utility, as a consumer consumes more of a good, the additional satisfaction or utility derived from each additional unit of the good decreases. In other words, the marginal utility of the good decreases as consumption increases.

This is because as a consumer consumes more of a good, their needs and wants are increasingly satisfied, and the importance or value of each additional unit diminishes. Therefore, the marginal utility derived from the good decreases at a decreasing rate.

Correct Answer: Ohm's

Solution : The correct answer is Ohm's Law.

Assuming that the temperature of a metallic wire stays constant, the potential difference across its ends in an electric circuit is directly proportional to the current passing through it. We refer to this as Ohm's law. Ohm's law states that the potential difference in a circuit is directly proportional to the current flowing through it. Resistance is the name given to the proportional constant. V = IR (where V is the potential difference, I is current, and R is resistance).

Correct Answer: Law of inertia

Solution : The correct option is the Law of inertia.

Newton's first law is also known as the law of inertia, highlighting the tendency of objects to maintain their state of motion or rest unless influenced by an external force. Newton's Second Law: Force equals mass times acceleration. Newton's Third Law: For every action, there is an equal and opposite reaction.

Correct Answer: Both the assertion and reason are true, and the reason is a correct explanation of the assertion.

Solution : The correct answer is (a) Option A Both the assertion and reason are true, and the reason is a correct explanation of the assertion.

The law of diminishing marginal utility states that as a consumer consumes more of a good, the additional satisfaction (or utility) derived from each additional unit of the good decreases. This occurs because the consumer's needs and wants for the good are limited. Initially, when the consumer has little or no units of the good, each additional unit provides a significant increase in satisfaction. However, as the consumer acquires more units, the marginal utility diminishes because the consumer's desire for the good becomes satiated. This means that the consumer's willingness to pay for additional units decreases, indicating a decrease in the additional satisfaction derived from each unit. Therefore, the reason provided correctly explains why the law of diminishing marginal utility occurs.
