$ Circinate ptyxis is found in Angiosperms.
! The male reproductive organs of Angiosperms are called antheridia.

Options

A. If both As and R are correct and R is correct explanation of As
B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

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

### Step 1: Analyze the Assertion
The assertion states that "Circinate ptyxis is found in Angiosperms."
- **Definition**: Circinate ptyxis refers to the coiling or curling of young leaves, which is a characteristic primarily observed in ferns and some gymnosperms.
- **Conclusion**: This assertion is incorrect because circinate ptyxis is not a feature of angiosperms; it is typically found in ferns and gymnosperms.

### Step 2: Analyze the Reason
The reason states that "The male reproductive organs of Angiosperms are called antheridia."
- **Definition**: In angiosperms, the male reproductive organs are called stamens, which consist of anthers and filaments. Antheridia, on the other hand, are the male reproductive structures found in bryophytes and some gymnosperms.
- **Conclusion**: This reason is also incorrect because it misidentifies the male reproductive organs of angiosperms.

### Step 3: Final Conclusion
Since both the assertion and the reason are incorrect, we conclude that the correct answer is that both the assertion and reason are wrong.
