Solution

The correct option is D To strongly hold the pollen grains
Gynoecium is the fourth whorl of a flower. Its individual unit is called megasporophyll or carpel. It consists of an ovary, stigma, and style. It is the female reproductive organ of the flower. The stigma is the top and sticky portion of a carpel or pistil that traps pollens. Hence it is the site of pollination.
So,option C is correct.
