Identify the mismatch statement regarding post-fertilization events from the following statement:

Options

A. Wall of the ovary is converted into pericarp
B. Outer integument is converted to inner pericarp
C. Triploid nucleus develops as endosperm
D. Ovary is developed as fruit

Answer

To identify the mismatch statement regarding post-fertilization events, let's analyze each of the provided statements step by step.

### Step-by-Step Solution:

1. **Understanding Post-Fertilization Events**:
- Post-fertilization events refer to the changes that occur after fertilization in plants. These events lead to the development of seeds and fruits.

2. **Analyzing Each Statement**:
- **Statement 1**: "Wall of the ovary is converted into pericarp."
- This statement is correct. The ovary wall develops into the fruit wall, known as the pericarp.

- **Statement 2**: "Outer integument is converted into inner pericarp."
- This statement is incorrect. The outer integument develops into the seed coat (testa), not the inner pericarp.

- **Statement 3**: "Triploid nucleus develops as endosperm."
- This statement is correct. The triploid nucleus, formed by the fusion of a male gamete with two polar nuclei, develops into the endosperm, which serves as a nutritive tissue for the developing embryo.

- **Statement 4**: "Ovary is developed as fruit."
- This statement is correct. After fertilization, the ovary develops into the fruit.

3. **Identifying the Mismatch**:
- From the analysis, the mismatch statement is **Statement 2**: "Outer integument is converted into inner pericarp." This is incorrect because the outer integument forms the seed coat (testa), not the inner pericarp.

### Conclusion:
The mismatch statement regarding post-fertilization events is: **"Outer integument is converted into inner pericarp."**
