Answer 2

The correct option is D

The plant is dioecious and bears only staminate flowers

Explanation:-

The most probable cause for the above situation is plant is dioecious and bears only staminate flowers.

The fruit may develop from a single ovary of a flower or simple fruit and several free carpels of a flower (total) or may form an entire inflorescence (multiple). Overall, fruits develop from the ovary. That is, a dioecious plant (bisexual) that has only staminate or male flowers will not produce fruit, while a dioecious plant that bears only pistillate and staminate fruits can have.

So, the correct answer is Plant is dioecious and bear only staminate flowers
