Options

A. The ovary wall develops into pericarp
B. The outer integument of the ovule develops into tegmen
C. The triple fusion nucleus develops into endosperm
D. The ovule develops into seed

Answer

To solve the question regarding the wrong statements about post-fertilization development, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Post-Fertilization Development**: Post-fertilization development refers to the processes that occur after fertilization, leading to the formation of seeds and fruits.

2. **Analyzing the First Statement**:
- **Statement**: "Ovary wall develops into pericarp."
- **Analysis**: This statement is **correct**. The ovary wall indeed develops into the pericarp, which is the part of the fruit that surrounds the seeds.

3. **Analyzing the Second Statement**:
- **Statement**: "The outer integument of the ovule develops into the tegmen."
- **Analysis**: This statement is **incorrect**. The outer integument of the ovule actually develops into the **testa**, not the tegmen. The tegmen is derived from the inner integument.

4. **Analyzing the Third Statement**:
- **Statement**: "The triple fusion nucleus develops into endosperm."
- **Analysis**: This statement is **correct**. The triple fusion nucleus, which is formed during fertilization, does indeed develop into the endosperm, which nourishes the developing embryo.

5. **Analyzing the Fourth Statement**:
- **Statement**: "The ovule develops into seed."
- **Analysis**: This statement is also **correct**. After fertilization, the ovule develops into a seed.

6. **Conclusion**:
- The wrong statement regarding post-fertilization development is **Option 2**: "The outer integument of the ovule develops into the tegmen."

### Final Answer:
The wrong statement regarding post-fertilization development is **Option 2**.
