Assertion`:-` Gemma cups are organs of perenniation in pteridophytes
Reason`:-` Gemmule produced in gemma cup are resistant against adverse condition.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertiion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are False

Explanation

To analyze the assertion and reason provided in the question, we can break down the solution into the following steps:

### Step 1: Understand the Assertion
The assertion states that "Gemma cups are organs of perennation in pteridophytes."
- **Evaluation**: Gemma cups are actually structures found in bryophytes, particularly liverworts (like Marchantia), and not in pteridophytes. Pteridophytes include ferns and horsetails, which do not have gemma cups.

### Step 2: Understand the Reason
The reason states that "Gemmules produced in gemma cups are resistant against adverse conditions."
- **Evaluation**: While it is true that gemmules (which are asexual reproductive structures) can be resistant to adverse conditions, they are not produced in gemma cups. Gemmules are produced by sponges, not by the structures in bryophytes.

### Step 3: Conclusion
Based on the evaluations:
- The assertion is **false** because gemma cups are not found in pteridophytes.
- The reason is also **false** because gemmules are not produced in gemma cups; they are produced by sponges.

### Final Answer
Both the assertion and the reason are false.
