Question

Assertion (A): Ovulation generally will not immediately occur following parturition.
Reason (R): Use of oral contraceptive pills inhibits ovulation.

• A. Both (A) and (R) are true. (R) is correct explanation for (A)
• B. Both (A) and (R) are true. (R) is not correct explanation for (A)
• C. (A) is true. But (R) is false
• D. (A) is false. But (R) is true

Hint:

Lactational amenorrhea is a natural contraceptive method.
It works because high prolactin levels block GnRH secretion, which is entirely different from the synthetic hormone feedback of oral contraceptive pills.

Answer 1

The Correct Option is B

Step 1: Judge the assertion on its own.
Right after childbirth ovulation is indeed suppressed for a while, this part is true.
Step 2: Judge the reason on its own.
Oral contraceptive pills do inhibit ovulation, so this statement is also true by itself.
Step 3: Check if the reason actually explains the assertion.
The real cause of post-partum ovulation suppression is high prolactin from breastfeeding blocking the hormonal signals needed for ovulation, not the use of contraceptive pills, which is a completely separate and unrelated mechanism.
Final answer: Option 2, both statements are true but R does not explain A.
