Where do ovarian follicles develop?

Ovarian follicles develop in the ovaries, which are the female reproductive organs responsible for producing eggs (ova) and hormones such as estrogen and progesterone. Each follicle consists of an immature egg surrounded by supportive cells. As follicles mature, they undergo a complex series of changes, including the development of the egg and the surrounding cells, leading to ovulation, when the mature egg is released into the fallopian tube.

The other options do not serve as the site of follicle development. The uterus is involved in the implantation and development of a fertilized egg, but not in the maturation of ovarian follicles. The fallopian tubes are where fertilization typically occurs and provide the pathway for the egg to travel from the ovary to the uterus, but they do not house developing follicles. The placenta is an organ that develops during pregnancy to nourish the fetus, unrelated to the development of ovarian follicles. Thus, the only correct choice regarding the site of follicle development is the ovaries.
