Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): Corpus luteum releases progesterone, small amount of estrogen and inhibin.
Reason (R): Under the influence of these hormones, the endometrial glands grow, become coiled and start uterine secretion.
In light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

Both statements are true, but the Reason explains an effect, not why the corpus luteum releases hormones.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept
After ovulation the ruptured follicle becomes the corpus luteum.

Step 2: Check the Assertion
The corpus luteum secretes large amounts of progesterone, a little estrogen and inhibin. So (A) is true.

Step 3: Check the Reason
In the secretory phase these hormones make the endometrial glands grow, coil and secrete. So (R) is true.

Step 4: Explanation test
The Reason gives the effect of the hormones on the uterus. It does not explain why the corpus luteum releases them, which is due to LH.

Final Answer:
Both are true but the Reason is not the correct explanation. \[ \boxed{\text{(B) }\text{Both (A) and (R) are true but (R) is NOT the correct explanation of (A).}} \]
