The correct option is B ii and iii
Water pollinated or hydrophilous flowers
(1) are colourless
(2) produce no nectar
(3) have pollen with a water proof mucilaginous coating
(4) long and ribbon like
Eg- Fresh water - Vallisneria and Hydrilla
Marine - Zostera or sea grasses

Water lily is not water-pollinated. Only very few dicots like Ceratophyllum demersum are hydrophillous.
