Solution

The correct option is C A is true but R is false
Grasses show anemophily (wind pollination) and their pollen grains are non sticky.
Plants that show wind pollination have light and non-sticky pollen grains so that they can be easily transported by the wind currents.
Hence A is true and R is false.
