Assertion :- Posterior lobe of pituitary gland secretes ADH & oxytocin.
Reason:- ADH & oxytocin are formed in hypothalamus also called-neurohormones.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Answer

To analyze the given assertion and reason, we will break it down step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that the posterior lobe of the pituitary gland secretes ADH (Antidiuretic Hormone) and oxytocin.
- This is true because the posterior pituitary, also known as the neurohypophysis, is responsible for the release of these two hormones.

2. **Understanding the Reason**:
- The reason provided states that ADH and oxytocin are formed in the hypothalamus and are referred to as neurohormones.
- This is also true. ADH and oxytocin are synthesized in the hypothalamus and then transported to the posterior pituitary for storage and release.

3. **Evaluating the Relationship**:
- Both the assertion and the reason are correct statements.
- However, while the reason explains where ADH and oxytocin are produced, it does not directly explain why the assertion about the posterior pituitary secreting these hormones is true.

4. **Conclusion**:
- Therefore, we conclude that both the assertion and the reason are correct, but the reason does not adequately explain the assertion.

### Final Answer:
Both the assertion and the reason are correct, but the reason does not explain the assertion correctly.
