AIIMS 2018 Zoology Contraceptive Methods Assertion Reason Question
Assertion: Cu T is a intrauterine device Reason: It decreases sperm motility.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not correct explanation of A
A is true but R is false
A and R are false
Correct Answer
Detailed Explanation
Cu T is indeed an intrauterine device (IUD) used for contraception, making the assertion true. However, the reason provided is false; Cu T primarily works by creating a hostile environment for sperm and preventing fertilization rather than directly decreasing sperm motility. Option A is incorrect because while both statements are true, the reason does not correctly explain the assertion. Option B is also incorrect as it claims R is a correct explanation. Option D is false since the assertion is true.
