Reason : vitamin C is essential for collgaen formation

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 but R is false
D. A is false but R is true.

Explanation

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

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Wounds heal slowly due to vitamin C deficiency."
- This implies that a lack of vitamin C in the body can lead to slower healing of wounds.

2. **Understanding the Reason**:
- The reason states that "Vitamin C is essential for collagen formation."
- This indicates that vitamin C plays a crucial role in the synthesis of collagen, which is a key protein in the body.

3. **Connecting the Assertion and Reason**:
- When a wound occurs, the body activates fibroblasts, which are specialized cells that produce collagen.
- Collagen is a major component of scar tissue, which is necessary for wound healing.
- If there is a deficiency of vitamin C, the formation of collagen will be impaired. As a result, the healing process will be delayed because the scar tissue cannot form properly.

4. **Conclusion**:
- Since the reason correctly explains why the assertion is true, we can conclude that both statements are correct.
- Therefore, the answer to the question is that both the assertion and the reason are true, and the reason is the correct explanation of the assertion.

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