Assertion: When embryo sac develops from magaspore mother cell, it is called diplospory,
Reason: In diplospory, two spores are formed.

Options

A. If both Assertion and Reason are true and Reason is corret explanation of Assertion
B. If both Assertion and Reason are true and Reason is not corret explanation of Assertion
C. If Assertion is true but Reason is false
D. If both Assertion and Reason are false

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that when the embryo sac develops from the megaspore mother cell, it is called diplospory. This is indeed correct. Diplospory refers to a type of asexual reproduction where the embryo sac develops directly from the megaspore mother cell without the typical meiotic process leading to the formation of multiple megaspores.

2. **Understanding the Reason**: The reason provided states that in diplospory, two spores are formed. This is incorrect. In diplospory, typically, the embryo sac develops from a single megaspore mother cell, and it does not involve the formation of two separate spores. Instead, it leads to the formation of a single functional megaspore that develops into the embryo sac.

3. **Evaluating the Truth of Assertion and Reason**:
- The assertion is true because it correctly describes diplospory.
- The reason is false because it incorrectly states that two spores are formed in diplospory.

4. **Conclusion**: Since the assertion is true and the reason is false, the correct option is that the assertion is true, but the reason is false.

### Final Answer:
- Assertion: True
- Reason: False
