Solution(By Examveda Team)

The pointed gourd is the dioecious plant among the following options.
A dioecious plant has either male or female flowers, not both. For dioecious plants to reproduce, a male plant must be near a female plant so that pollinators can do their work.
Trichosanthes dioica, also known as the pointed gourd is a vine plant in the family Cucurbitaceae, similar to cucumber and squash, though unlike those it is perennial.
It is a dioecious (male and female plants) vine (creeper) plant with heart-shaped leaves (cordate) and is grown on a trellis. The fruits are green with white or no stripes. Size can vary from small and round to thick and long 2 to 6 inches. It thrives well under a hot to moderately warm and humid climate.
