Assertion: Fruits are formed only in angiosperms.
Reason: Fruits develop from ovaries which are found only in angiosperms.

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that "Fruits are formed only in angiosperms." To evaluate this, we need to consider what fruits are and which plant groups produce them.

2. **Definition of Fruits**: Fruits are the mature ovary of a flower, which typically contains seeds. They develop after fertilization when the ovule is fertilized by the male gamete.

3. **Identifying Plant Groups**: There are four main groups of plants:
- Angiosperms (flowering plants)
- Gymnosperms (non-flowering plants with seeds)
- Pteridophytes (ferns and their relatives)
- Bryophytes (mosses and liverworts)

4. **Fruits in Angiosperms**: In angiosperms, the flower contains a structure called the pistil, which includes the ovary. After fertilization, the ovary develops into a fruit, which protects the seeds and aids in their dispersal.

5. **Fruits in Other Plant Groups**:
- **Gymnosperms**: These plants produce seeds but do not form fruits. Their seeds are exposed and not enclosed within an ovary.
- **Pteridophytes and Bryophytes**: These groups do not produce flowers or fruits at all. They reproduce via spores and do not have a structure analogous to fruits.

6. **Conclusion on the Assertion**: Since fruits are indeed formed only in angiosperms and not in gymnosperms, pteridophytes, or bryophytes, the assertion is true.

7. **Understanding the Reason**: The reason states that "Fruits develop from ovaries which are found only in angiosperms." This is also true because the ovary is a structure specific to flowering plants (angiosperms) that develops into fruit.

8. **Conclusion on the Reason**: Since the reason correctly explains why the assertion is true, both the assertion and reason are true, and the reason is the correct explanation of the assertion.

9. **Final Answer**: Therefore, the correct option is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.
