Assertion:Fruit is the mature or ripened ovary developed after fertilisation.
Reason:Fruit formed without fertilisation of the ovary is called parthenocarpic fruit.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If assertion and reason are false.

Answer

To solve the question, we need to analyze the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Fruit is the mature or ripened ovary developed after fertilization."
- This statement is true. In flowering plants, after the fertilization of the ovule, the ovary matures into a fruit, which often contains seeds.

2. **Understanding the Reason**:
- The reason states that "Fruit formed without fertilization of the ovary is called parthenocarpic fruit."
- This statement is also true. Parthenocarpy refers to the development of fruit without fertilization, resulting in seedless fruits.

3. **Analyzing the Relationship**:
- While both the assertion and the reason are true, the reason does not explain the assertion. The assertion specifically describes the typical process of fruit development involving fertilization, while the reason describes an alternative process (parthenocarpy) that does not involve fertilization.

4. **Conclusion**:
- Since both statements are true but the reason does not correctly explain the assertion, the correct answer is that both assertion and reason are true, but the reason is not the correct explanation of the assertion.

### Final Answer:
The correct option is B: Both assertion and reason are true, but reason is not the correct explanation of assertion.
