When centrolecithal egg of the insects divides regularly then what will happen

Options

A. Cells surround the yolk
B. Yolk surround the cells
C. Yolk lie below the group of cells
D. Yolk lie above the group of cells

Explanation

### Step-by-Step Solution:

1. **Understanding Centrolecithal Eggs**:
- Centrolecithal eggs are characterized by having a large amount of yolk concentrated in the center of the egg, surrounded by a thin layer of cytoplasm. This type of egg is commonly found in insects.

2. **Regular Division of Centrolecithal Eggs**:
- When centrolecithal eggs undergo regular division (cleavage), the process is different from that seen in other types of eggs (like isolecithal or telolecithal). In centrolecithal eggs, the cleavage is superficial because the yolk is concentrated in the center and the cytoplasm is on the periphery.

3. **Outcome of Regular Division**:
- As the egg divides, the cells will form around the yolk. The cleavage furrows do not penetrate the yolk but instead create a layer of cells that surround the yolk mass.

4. **Conclusion**:
- Therefore, when a centrolecithal egg of an insect divides regularly, the cells will surround the yolk.

5. **Correct Answer**:
- The correct option is that the cells surround the yolk.
