Solution

The correct option is B Epihydrophily
Pollination in Vallisneria is epihydriphilous. It is a type of hydrophily which occurs on the surface of water. The female flower have a very long pedicel, therefore it reaches the surface of water. Male flowers after breakage floats on the surface of water. Pollen grains are released on to the surface of water. They are carried passively by water currents, some of them eventually reach the female flowers and the stigma.
