The correct option is B Ficus — Anemophily
Pollination by wind is called anemophily.
Ficus is pollinated by insects where an insect lays eggs in the ovary of the flowers and in turn the pollen grains stick to the body of the insect which then becomes a pollinating agent. Hence, insect is the pollinating agent, not wind.
Yucca is pollinated by the yucca moth, also called Pronuba moth.
Salvia exhibits protandry or maturation of the male reproductive structures before the female reproductive structures.
Cleistogamy is the self pollination that happens within a floral bud before it opens. This is observed in Viola.
