Assertion: In pteridophyte well distinct alternation of generation is present.
Reason: In pteridophytes both gametophyte and sporophyte are independent.

Options

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

Answer

To analyze the given assertion and reason, we will break down the concepts of pteridophytes and their life cycle step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that in pteridophytes, a well-distinct alternation of generations is present.
- In pteridophytes, there is indeed a clear alternation between two generations: the sporophyte (diploid) and the gametophyte (haploid).

2. **Understanding the Reason**:
- The reason states that in pteridophytes, both gametophyte and sporophyte are independent.
- This is also true. In pteridophytes, the gametophyte and sporophyte generations grow independently of each other. The gametophyte is typically small and produces gametes, while the sporophyte is larger and produces spores.

3. **Connecting Assertion and Reason**:
- The assertion claims that there is a distinct alternation of generations, while the reason explains that both generations are independent.
- The independence of these generations supports the assertion because it emphasizes the distinct nature of each generation in the life cycle of pteridophytes.

4. **Conclusion**:
- Both the assertion and reason are true, and the reason correctly explains the assertion. Therefore, we conclude that the assertion is true, the reason is true, and the reason is the correct explanation of the assertion.

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