Give below are assertion and reason. Point out if both are true and reason is correct explanation (A), both true but reason is not correct explanation (B), assertion is true but reason is wrong (C), both are wrong (D). Assertion: Megaspore mother cell undergoes meiosis to produce four megaspores. Reason: Megaspore mother cells and megaspores both are haploid

Options

A. A
B. B
C. C
D. D.

Answer

To solve the question regarding the assertion and reason provided, we will analyze both statements step by step.

### Step 1: Analyze the Assertion
- **Assertion**: "Megaspore mother cell undergoes meiosis to produce four megaspores."
- **Explanation**: The assertion states that the megaspore mother cell (MMC) undergoes meiosis. This is indeed true because the MMC is diploid (2n) and it undergoes meiosis, which is a reductional division that results in the formation of four haploid megaspores (n).

### Step 2: Analyze the Reason
- **Reason**: "Megaspore mother cells and megaspores both are haploid."
- **Explanation**: This statement is incorrect. The megaspore mother cell is diploid (2n), while the megaspores produced after meiosis are haploid (n). Therefore, the reason provided is false.

### Step 3: Conclusion
- Since the assertion is true and the reason is false, we can conclude that the correct answer is:
- **Option C**: Assertion is true but reason is wrong.
