Answer 1

The correct option is A $III$ and $IV$

Pollen grains
Pollen grains of submerged water pollinated plants are ribbon-like whereas wind pollinated flowers have dry, small and light pollen grains to be carried by wind.
Stigma
Stigma of a wind pollinated or anemophilous flower is long and feathery to trap pollen from the air.
Hydrophilous or water-pollinated plants have a long and sticky stigma.
Flowers
Common features of wind and water pollinated plants are as follows:
$\bullet$Flowers are colourless and odourless.
$\bullet$Flowers do not form and store nectar.
This is because they don't need to attract insects to pollinate them.
Final answer
(A) $III$ and $IV$
