AIIMS 2019 Biology Nutritional Deficiencies Assertion Reason Question
Assertion: Iodine deficiency may lead to irregular menstrual cycle
Reason: Estrogen and progesterone level becomes low

Both assertion and reason are true, but reason is not the correct explanation of assertion.
Assertion is true, but reason is false.
Both assertion and reason are false.
Correct Answer
Detailed Explanation
Option C is correct because the assertion accurately states that iron deficiency can lead to abnormalities in the menstrual cycle, while the reason incorrectly claims that levels of estrogen and progesterone do not decrease; in fact, hormonal imbalances can occur due to various factors, including nutritional deficiencies. Option A is incorrect because the reason is false, so it cannot be the correct explanation for the assertion. Option B is also incorrect because, while both statements are true, the reason does not explain the assertion. Lastly, option D is incorrect as the assertion is true, making both statements not false.
