Options

A. (a) Tegmen
B. (b) Perisperm
C. (c) Testa
D. (d) Pericarp (fruit)

Answer

To answer the question, "Upon fertilization, while the ovule develops into a seed, what structure develops from the carpel?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Carpel**: The carpel is the female reproductive part of a flower, consisting of three main parts: stigma, style, and ovary.

2. **Fertilization Process**: During fertilization, the male gamete (pollen) fuses with the female gamete (egg cell) located in the ovule. This process leads to the formation of a zygote.

3. **Development of the Ovule**: After fertilization, the ovule develops into a seed. The seed contains the embryo, which will grow into a new plant.

4. **Transformation of the Carpel**: The carpel, specifically the ovary part, undergoes a transformation after fertilization. The ovary develops into a fruit, which is known as the pericarp.

5. **Conclusion**: Therefore, the structure that develops from the carpel upon fertilization is the **pericarp** (fruit).

### Final Answer:
The structure that develops from the carpel upon fertilization is the **pericarp**.
