[A] : Pancreas is the second largest of the di- gestive glands.
[R]: It plays a dual role in the body serving as both exocrine and an endocrine gland.
a) If both A and R are true and R is the correct explanation of A
b) If both A and R are true but R is not the correct explanation of A
c) If A is true and R is false
d) If both A and R are false

Options

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

Answer

To solve the question regarding the statements about the pancreas, we will analyze both statements step by step.

### Step-by-Step Solution:

1. **Understanding Statement A**:
- Statement A claims that "Pancreas is the second largest of the digestive glands."
- This statement is true. The liver is the largest digestive gland, and the pancreas is indeed the second largest.

2. **Understanding Statement R**:
- Statement R states that "It plays a dual role in the body serving as both exocrine and endocrine gland."
- This statement is also true. The pancreas functions as an exocrine gland by secreting digestive enzymes and as an endocrine gland by producing hormones like insulin and glucagon.

3. **Analyzing the Relationship Between A and R**:
- While both statements A and R are true, we need to determine if R explains A.
- Statement A discusses the size of the pancreas among digestive glands, while Statement R discusses its functional roles.
- There is no direct causal relationship where R explains why A is true. The size of the pancreas does not depend on its dual role.

4. **Conclusion**:
- Since both statements are true but R does not explain A, the correct answer is:
- **Option B**: If both A and R are true but R is not the correct explanation of A.
