Hydrophily is found in

Options

A. Potamogeton
B. Myriophyllum
C. Nymphaea
D. Zostera

Answer

To determine which of the given options represents a plant that exhibits hydrophily (pollination through water), we can follow these steps:

### Step-by-Step Solution:

1. **Understand Hydrophily**: Hydrophily refers to the process of pollination that occurs through water. This is a form of pollination seen in certain aquatic plants.

2. **Analyze the Options**: The options provided are:
- Pomatogeton
- Myriophyllum
- Nymphaea
- Zostera

3. **Identify Aquatic Plants**: All the options listed are aquatic plants, but we need to determine which one is specifically known for hydrophily.

4. **Research Each Option**:
- **Pomatogeton**: This genus includes several species of aquatic plants, but they are primarily known for wind pollination (anemophily).
- **Myriophyllum**: This is another aquatic plant that also relies on wind for pollination.
- **Nymphaea**: Commonly known as water lilies, these plants are typically pollinated by insects (entomophily).
- **Zostera**: Also known as eelgrass, Zostera is a true hydrophilous plant, as it relies on water for the transfer of pollen.

5. **Conclusion**: After evaluating the options, Zostera is the only plant that exhibits hydrophily.

### Final Answer:
The correct answer is **Zostera**.
