In a majority of aquatic plants such as water hyacinth and water lily, the flowers emerge above the level of water and are pollinated by insects or wind as in most of the land plants. Their stem part which is above the thalamus is not in the water. The pollen grains are in the upper part of thalamus so pollination can't done by water. That's why it is done by insects and wind.

Pollination in Water Hyacinth and Water Lily
Pollination is the process of transfer of pollen grains from the anther of a flower to the stigma of the same or another flower. Water hyacinth and water lily are two aquatic plants that are dependent on external agents for pollination.
External agents responsible for pollination:
- Insects
- Wind
- Water
Pollination in Water Hyacinth:
Water hyacinth is an aquatic plant that floats on the surface of water. The flowers of water hyacinth are large and showy, and they are pollinated by insects such as bees, butterflies, and moths. The pollinators are attracted to the flowers by their bright colours and sweet nectar. When the insects land on the flower, they transfer pollen from the anthers to the stigma, which results in pollination.
Pollination in Water Lily:
Water lily is another aquatic plant that is found in ponds and lakes. The flowers of water lily are also large and showy, and they are pollinated by insects such as bees, beetles, and flies. The pollinators are attracted to the flowers by their sweet scent and bright colours. When the insects land on the flower, they transfer pollen from the anthers to the stigma, which results in pollination.
Conclusion:
Hence, the correct answer is option 'C' - Insects or wind. Though water is also an external agent responsible for pollination, it is not the only agent involved in the pollination of water hyacinth and water lily.
