Assertion: Neurohypophysis is situated in the cells of stomach.
Reason: Neurohypophysis synthesizes vasopressin and oxytocin.

Options

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

Explanation

To solve the question regarding the assertion and reason provided, we need to analyze both statements carefully.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Neurohypophysis is situated in the cells of the stomach."
- The neurohypophysis, also known as the posterior pituitary, is not located in the stomach. It is actually situated in the brain, specifically in a bony cavity called the sella turcica. Therefore, this assertion is **false**.

2. **Understanding the Reason**:
- The reason states that "Neurohypophysis synthesizes vasopressin and oxytocin."
- While the neurohypophysis does release vasopressin (also known as antidiuretic hormone) and oxytocin, it does not synthesize these hormones. Instead, these hormones are synthesized in the hypothalamus and then transported to the neurohypophysis for storage and release. Therefore, this reason is also **false**.

3. **Conclusion**:
- Since both the assertion and the reason are false, the correct answer to the question is that both the assertion and reason are false.

### Final Answer:
Both the assertion and reason are false.
