Dear,

If you have a confusion in choosing the Correct option it means that you are not clear on the Concept. May be you are good in Biology, but the questions are designed in such a way so as to confuse you and pick up a wrong answer Choice. So you should be very clear about the Concept and confident about your answer. Then you will improve your Accuracy.
