The wall of the ovary forms

Options

A. pericarp
B. fruit wall
C. fruit
D. both (a) and (b).

Explanation

**Step-by-Step Solution:**

1. **Understanding the Ovary Structure**: The ovary is a part of the female reproductive system in plants, which contains ovules. After fertilization, these ovules develop into seeds.

2. **Role of the Ovary Wall**: The wall of the ovary plays a crucial role after fertilization. It surrounds the ovules and protects them as they develop into seeds.

3. **Formation of the Fruit**: After fertilization occurs, the ovary wall transforms into the fruit wall, which is scientifically referred to as the pericarp. This process is essential for the protection and nourishment of the developing seeds.

4. **Terminology**: The term "pericarp" refers specifically to the layers of the fruit wall that develop from the ovary wall. It consists of three layers: exocarp (outer layer), mesocarp (middle layer), and endocarp (inner layer).

5. **Conclusion**: Therefore, the wall of the ovary forms both the pericarp and the fruit wall after fertilization. This means that the correct answer to the question is that the wall of the ovary forms both A (pericarp) and B (fruit wall).

**Final Answer**: The wall of the ovary forms both pericarp and fruit wall (both A and B).
