Eyes of potato are useful for

Options

A. nutrition
B. respiration
C. reproduction
D. vegetative propagation

Explanation

### Step-by-Step Solution:

1. **Understanding Potato Eyes**: The "eyes" of a potato are small buds located on the surface of the potato tuber. Each eye has the potential to develop into a new potato plant.

2. **Function of Eyes**: The primary function of the eyes is to facilitate vegetative propagation. This means that new potato plants can grow from these buds without the need for seeds.

3. **Asexual Reproduction**: The process by which potatoes reproduce through their eyes is a form of asexual reproduction. This is different from sexual reproduction, which involves the fusion of gametes.

4. **Vegetative Propagation**: In vegetative propagation, the new plants are genetically identical to the parent plant. This is advantageous for farmers as it allows for the cultivation of uniform crops.

5. **Practical Implication**: When a potato is planted in the soil, the eyes will sprout and grow into new potato plants, leading to the production of more potatoes.

6. **Conclusion**: Therefore, the eyes of the potato are useful for vegetative propagation, allowing the plant to reproduce asexually and produce new tubers.
