Free nuclear division occurs in

Options

A. Flower
B. endosperm
C. gametes
D. fruit

Explanation

To solve the question "Free nuclear division occurs in," we will analyze the options provided and determine which one is correct based on biological concepts.

### Step-by-Step Solution:

1. **Understanding Free Nuclear Division**:
- Free nuclear division refers to the process where the nucleus divides multiple times without the formation of a cell wall between the divisions. This leads to the formation of multiple nuclei within a single cell.

2. **Analyzing the Options**:
- **Flower**: Flowers are the reproductive structures of plants where fertilization occurs. They do not primarily involve free nuclear division.
- **Endosperm**: The endosperm is a tissue that provides nourishment to the developing embryo in seeds. It is formed after fertilization and is known to undergo free nuclear division.
- **Gametes**: Gametes (sperm and egg cells) are involved in sexual reproduction but do not undergo free nuclear division.
- **Fruit**: Fruits develop from the fertilized ovary of a flower and do not involve free nuclear division.

3. **Identifying the Correct Answer**:
- The endosperm is formed from the primary endosperm nucleus, which results from the fusion of a male gamete and a secondary nucleus. During the development of the endosperm, multiple nuclear divisions occur without the formation of cell walls, which is characteristic of free nuclear division.

4. **Conclusion**:
- Based on the analysis, the correct answer to the question "Free nuclear division occurs in" is **Endosperm**.

### Final Answer:
**Endosperm**
