B. seagrass
C. water lily
D. common pansy

Answer

To determine which of the following is a water-pollinated plant, we will analyze each option provided:

1. **Understanding Water Pollination**:
- Water pollination, or hydrophily, occurs when pollen is carried by water to the stigma of flowers. This is a specific type of pollination that is distinct from pollination by wind or insects.

2. **Analyzing the Options**:
- **Option A: Water Hyacinth**: This plant is primarily pollinated by insects, not by water. Therefore, it does not qualify as a water-pollinated plant.
- **Option B: Seagrass**: Seagrass is known to be a water-pollinated plant. It undergoes hydrophilous pollination, where pollen is carried by water to fertilize the flowers.
- **Option C: Water Lily**: Water lilies are generally pollinated by insects, although they do grow in water. They do not rely on water for the transfer of pollen.
- **Option D: Common Pansy**: This plant is also pollinated by insects and does not utilize water for pollination.

3. **Conclusion**:
- After analyzing all the options, the only plant that is classified as a water-pollinated plant is **Option B: Seagrass**.

**Final Answer**: The correct answer is **Option B: Seagrass**.
