Identify the part of the flower where fruits develops in members of phylum anthophyta.

Ovary

Explanation:

Anthophyta or the angiosperm are the plants which bear reproductive structure in a colorful modified shoot called flower.

The flower contains both male and female reproductive structures. It is the female reproductive structure that develops into the fruits when the female egg cell is fertilized with the sperm.

The female reproductive structure is made of the style, stigma and the ovary. The ovary encloses the egg cell which after fertilization becomes an embryo and the ovule turns into the seed and the ovary turns into the fruits. That is why the fruits bear the seeds.

Thus, the ovary is correct.
