Solution

The correct option is C
Unisexual

The flowers that have reproductive organs of only one sex are called unisexual flowers. The stamens and carpels are the reproductive part of flowers while the calyx and corolla are the accessory organs. When only pistil is present in the flower, it is called pistillate flower and when only stamens are present it is called staminate.
