Assertion: Pancreas is a heterocrine gland.
Reason: Endocrine part secretes insulin and glucagon and exocrine part secretes an acidic pancreatic juice containing enzymes.

Options

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

Explanation

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that the pancreas is a heterocrine gland. A heterocrine gland is one that has both endocrine and exocrine functions.

2. **Identifying the Functions of the Pancreas**:
- **Endocrine Function**: The pancreas secretes hormones such as insulin and glucagon directly into the bloodstream. This is the endocrine function.
- **Exocrine Function**: The pancreas also produces pancreatic juice, which contains digestive enzymes, and secretes it into the small intestine through ducts. This is the exocrine function.

3. **Analyzing the Reason**: The reason provided states that the endocrine part secretes insulin and glucagon, which is correct. However, it also states that the exocrine part secretes an "acidic" pancreatic juice. This is incorrect because the pancreatic juice is actually alkaline, not acidic.

4. **Conclusion**:
- The assertion is true because the pancreas is indeed a heterocrine gland.
- The reason is false because it incorrectly describes the nature of the pancreatic juice as acidic instead of alkaline.

5. **Final Answer**: Therefore, the correct option is that the assertion is true, but the reason is false.
