Correct Answer: Praseodymium

Solution : The correct option is Praseodymium.

Praseodymium is a chemical element with the symbol Pr and atomic number 59. It is a member of the lanthanide series, which is a group of 15 elements located in the f-block of the periodic table. Praseodymium, like many lanthanides, is a soft and malleable metal. This means it can be easily shaped or deformed under pressure.

Praseodymium exhibits a silvery-yellow or pale greenish-yellow colour, which can make it visually distinct when compared to other elements.

Correct Answer: (2)

Solution : The correct choice is the second option.

The sentence is in the past perfect tense, as it is telling about an event that was completed after a past event. Thus, the correct usage is "he had to get" in place of "he must have".

Therefore, the correct sentence is: The arm was so badly injured that he had to get it amputated.
