Given below are assertion and reason. Point out if both are true with reason being correct explanation (A), both are true but reason is not correct explanation (B), assertion is true but reason is wrong (C) both are wrong (D) . Assertion: In some species of asteraceae and poaceae, seeds are formed without fertilization Reason:Formation of fruit without fertilization is called parthenocarpy

Options

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

Answer

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

### Step-by-Step Solution:

1. **Understanding the Assertion:**
- The assertion states that in some species of Asteraceae and Poaceae, seeds are formed without fertilization.
- This phenomenon is known as apomixis, where seeds develop from the ovule without the fertilization process.

2. **Understanding the Reason:**
- The reason given is that the formation of fruit without fertilization is called parthenocarpy.
- Parthenocarpy refers to the development of fruit without fertilization, which typically results in seedless fruits.

3. **Evaluating the Truth of the Assertion:**
- The assertion is true because apomixis does occur in certain species of Asteraceae (like sunflowers) and Poaceae (like wheat), allowing seeds to form without fertilization.

4. **Evaluating the Truth of the Reason:**
- The reason is also true as parthenocarpy does involve the formation of fruit without fertilization. However, it is important to note that parthenocarpy does not lead to the formation of seeds.

5. **Determining the Relationship Between Assertion and Reason:**
- While both statements are true, the reason does not correctly explain the assertion. The assertion is specifically about seed formation (apomixis), whereas the reason discusses fruit formation (parthenocarpy), which is a different process.

### Conclusion:
- Since both the assertion and reason are true, but the reason does not correctly explain the assertion, the correct option is **B**: both are true but reason is not the correct explanation.
