C. Pollen
Explanation
The male papaya tree never produces fruit because it only produces pollen. Pollen is the male reproductive cell of the plant, which is transferred to the female flowers for fertilization. While the female papaya tree produces fruit, the male tree's main role is to produce pollen to facilitate pollination and reproduction in the species.
5.
