The correct option is A Grasses
Anemophily is the type of pollination in which wind is the pollinating agent. The pollen grains are light and non-sticky so that they can easily be carried by air currents. The flowers have well-exposed stamens so that the pollens are easily dispersed into wind currents. Flowers have a large feathery stigma to easily trap the airborne pollen grains. It occurs in grasses, maize, wheat, etc.
