B. 2 and 3
C. 2 only
D. all of them ​​​

Answer 1

Answer :-

Insect-pollinated flowers usually possess sticky and heavy pollens with a rough surface that allow them to stick to insects easily.

Flowers also have sweet nectar that attracts insects that go from flower to flower to pollinate the flowers.

The pollen grains are also in small quantities, because it is very likely that insects will enter another flower, and the pollen grains would have a higher chance of landing on the stigma.

That's why there is no need of pollen grains in large quantities.
