Options

B. plant is dioecious and bears both pistillate and staminate flowers
C. plant is monoecious
D. plant is dioecious and bears only staminate flowers.

Answer

D

Explanation

Fruits can develop from a single ovary of a single flower (simple fruit) or from several free carpels of a single flower (aggregate) or from whole inflorescence (multiple). In total, fruits develop from ovaries. This is why a dioecious plant (unisexual) bearing only staminate(male) flowers will not produce fruits, whereas monoecious plants (bisexual) or dioecious plant bearing only pistillate (female) flowers or pistillate and staminate both can bear fruits.
