Assertion : Insulin is antagonistic to glucagon.
Reason : It is an anabolic hormone.

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.

Explanation

To analyze the given assertion and reason, we can break down the information step by step:

### Step 1: Understand the Assertion
- **Assertion**: Insulin is antagonistic to glucagon.
- **Explanation**: This means that insulin and glucagon have opposite effects in the body. Insulin lowers blood glucose levels, while glucagon raises them.

**Hint**: Remember that antagonistic hormones have opposing functions in regulating bodily processes.

### Step 2: Understand the Reason
- **Reason**: Insulin is an anabolic hormone.
- **Explanation**: An anabolic hormone promotes the building up of complex molecules from simpler ones. Insulin facilitates the conversion of glucose into glycogen (storage form of glucose) and promotes protein synthesis.

**Hint**: Anabolic processes involve building up, while catabolic processes involve breaking down.

### Step 3: Analyze the Relationship
- Insulin's role as an anabolic hormone supports the assertion that it is antagonistic to glucagon. While glucagon promotes the breakdown of glycogen to glucose (catabolic), insulin promotes the storage of glucose as glycogen (anabolic).

**Hint**: Consider how the functions of each hormone relate to their roles in metabolism.

### Step 4: Conclusion
- Both the assertion and the reason are true, and the reason correctly explains the assertion. Insulin's anabolic nature is what makes it functionally opposite to glucagon.

**Final Answer**: Both assertion and reason are true, and the reason is the correct explanation of the assertion.

### Summary of Steps:
1. Identify the assertion and its meaning.
2. Identify the reason and its meaning.
3. Analyze how the reason supports the assertion.
4. Conclude whether both statements are true and if the reason explains the assertion.
