Assertion : Seeded plants are highly evolved.
Reason : In spermatophyta, seeds are formed .

Options

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

Answer

### Step-by-Step Text Solution:

1. **Understanding the Assertion**: The assertion states that "Seeded plants are highly evolved." This is generally accepted in the field of botany, as seeded plants, particularly angiosperms (flowering plants), exhibit advanced features such as complex reproductive structures and mechanisms.

2. **Understanding the Reason**: The reason provided is that "In spermatophyta, seeds are formed." Spermatophyta, which includes both gymnosperms and angiosperms, is indeed characterized by the formation of seeds. This is a significant evolutionary advancement over non-seeded plants.

3. **Evaluating the Relationship**: While both the assertion and the reason are true, the reason does not adequately explain why seeded plants are considered highly evolved. The assertion implies a broader context of evolution that includes various reproductive strategies and adaptations found in angiosperms, such as double fertilization and the development of fruits and flowers.

4. **Conclusion**: Since the reason is true but does not serve as the correct explanation for the assertion, we conclude that the assertion is true, and the reason is true but not the correct explanation.

5. **Choosing the Correct Option**: Based on the evaluation, the correct answer would be that both the assertion and reason are true, but the reason is not the correct explanation for the assertion.

### Final Answer:
The correct option is: Both assertion and reason are true, but reason is not the correct explanation of assertion.
