The correct Answer is:
To analyze the given assertion and reason, we can break down the information step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that in gymnosperms, the male and female gametophytes do not have independent existence. - This means that the gametophytes are not free-living and rely on the sporophyte for their existence. 2. **Understanding the Reason**: - The reason provided states that the male and female gametophytes remain within the sporangia retained on the sporophyte. - This indicates that the gametophytes are enclosed within structures (sporangia) that are part of the sporophyte generation. 3. **Evaluating the Assertion**: - The assertion is true because in gymnosperms, the gametophytes (both male and female) are indeed dependent on the sporophyte and do not exist independently. 4. **Evaluating the Reason**: - The reason is also true because it accurately describes the situation where the gametophytes are retained within the sporangia on the sporophyte. 5. **Conclusion**: - Since both the assertion and the reason are true, and the reason correctly explains the assertion, we conclude that the correct answer is that both the assertion and reason are true, and the reason is the correct explanation of the assertion. ### Final Answer: Both the assertion and reason are true, and the reason is the correct explanation of the assertion. ---
