Assertion (A) Polyembryony phenomenon is more common in gymnosperm than angiosperms.
Reason (R) In angiosperms the polyembryony is generally present as unusual feature.

Options

A. Both Assertion and reason are correct, and Reason is the correct explanation of Assertion.
B. Both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
C. Assertion is correct, but Reason is incorrect
D. Assertion is incorrect, but Reason is correct

Answer

To solve the assertion-reason question, we need to analyze both the assertion (A) and the reason (R) provided.

### Step 1: Understand the Assertion
The assertion states that "Polyembryony phenomenon is more common in gymnosperms than angiosperms."
- **Polyembryony** refers to the occurrence of multiple embryos developing from a single fertilized egg.
- It is indeed true that polyembryony is more frequently observed in gymnosperms compared to angiosperms.

### Step 2: Understand the Reason
The reason states that "In angiosperms, polyembryony is generally present as an unusual feature."
- While polyembryony can occur in angiosperms, it is not as common and is often seen as an unusual occurrence.
- This statement is also true, as polyembryony in angiosperms is relatively rare and typically occurs under specific conditions.

### Step 3: Evaluate the Relationship
Now we need to determine if the reason (R) justifies the assertion (A).
- Since the assertion is that polyembryony is more common in gymnosperms, and the reason explains that in angiosperms, it is an unusual feature, the reason does support the assertion.
- The rarity of polyembryony in angiosperms compared to gymnosperms helps to justify the assertion.

### Conclusion
Both the assertion and the reason are true, and the reason provides a valid explanation for the assertion. Therefore, the correct answer is that both statements are true, and the reason supports the assertion.

### Final Answer
Both the assertion (A) and the reason (R) are true, and R justifies A.
