Identify the set of correct statements:
A. The flowers of Vallisneria are colourful and produce nectar.
B. The flowers of waterlily are not pollinated by water.
C. In most of water-pollinated species, the pollen grains are protected from wetting.
D. Pollen grains of some hydrophytes are long and ribbon like.
E. In some hydrophytes, the pollen grains are carried passively inside water.

Vallisneria flowers are small and inconspicuous and are pollinated at the water surface — they are not colourful nor do they produce nectar; A is wrong. Water lily, though aquatic, is insect / wind pollinated (B correct). Pollen of water-pollinated species is protected from wetting by a mucilaginous covering (C). Some water-pollinated pollen grains are ribbon-like (D), and many are carried passively in water currents (E). So B, C, D and E are correct.
