Assertion : When embryo sac develops from megaspore mother cell without meiosis it is called diplospory.
Reason : Fruits are formed without seeds in diplospory

Options

A. Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion
B. The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion.
C. Assertion is true but the Reason is false
D. Both the statements are false.

Answer

### Step-by-Step Text Solution:

1. **Understanding the Assertion**:
- The assertion states that when the embryo sac develops from the megaspore mother cell without undergoing meiosis, it is termed as diplospory. This is accurate as diplospory is a form of apomixis where the embryo sac develops directly from the megaspore mother cell through mitosis instead of meiosis.

2. **Understanding the Reason**:
- The reason provided claims that fruits are formed without seeds in diplospory. This statement is misleading. While diplospory allows for the formation of an embryo sac without meiosis, it does not imply that the resulting fruits are seedless. In fact, fruits can still develop from seeds formed through apomictic processes.

3. **Evaluating the Truth of Both Statements**:
- The assertion is true because it correctly describes diplospory.
- The reason is false because it incorrectly states that fruits are formed without seeds in diplospory.

4. **Conclusion**:
- Therefore, the final evaluation is that the assertion is true, but the reason is false.

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