Assertion : Inhibin is secreted by the corpus luteum.
Reason : They inhibit the FSH and GnRH production.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion then mark (2).
C. If Assertion is true statement but Reason is false, then mark (3).
D. If both Assertion and Reason are false statements, then mark (4)

Answer

To analyze the given question, we will break it down into its components: the assertion and the reason.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Inhibin is secreted by the corpus luteum."
- The corpus luteum is a structure formed from the follicle after ovulation and is responsible for producing hormones, including inhibin.

2. **Evaluating the Assertion**:
- The statement is **true** because the corpus luteum does secrete inhibin, which plays a role in the reproductive cycle.

3. **Understanding the Reason**:
- The reason states that "They inhibit the FSH and GnRH production."
- Inhibin primarily functions to inhibit the secretion of Follicle-Stimulating Hormone (FSH) from the anterior pituitary gland. It does not directly inhibit Gonadotropin-Releasing Hormone (GnRH) production.

4. **Evaluating the Reason**:
- The statement is **partially true**. While inhibin does inhibit FSH, it does not directly inhibit GnRH production. Therefore, the reason provided does not accurately explain the assertion.

5. **Conclusion**:
- Since both the assertion and the reason are true, but the reason does not correctly explain the assertion, we conclude that the correct answer is option 2: "If both assertion and reason are true but the reason is not the correct explanation of the assertion."

### Final Answer:
The correct option is **2**.
