Solution

The correct option is D Plant is dioecious and bears only staminate flowers
Fruits can develop from a single ovary of a single flower(simple fruit) or from several free carpels of a single flower (aggregate) or form 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 plants bearing only pistillate (female) lowers or pistillate and staminate both can bear fruits. So, the correct answer is 'Plant is dioecious and bears only staminate flowers'.
