Answer 1

The correct option is C

Hydrophilous flowers are always submerged in water

Pollination through water as the agent is hydrophilly. For hydrophilly to take place there are certain characteristics to be exhibited by the plant like hydrophilous flowers are not colourful and they do not produce nectar. They produce numerous and naked pollen grains lacking the outer covering exine. However, they are surrounded by mucilage covering to protect them from getting wet. Their gynoecium contains a sticky stigma to increase the chances of catching the pollen grains. Hydrophilous flowers are not always submerged in water for example flowers of Vallisneria float on the water surface and are pollinated by water currents.
