Answer 1

The correct option is A Primary follicle

A primary follicle is surrounded by single or several layers of cuboidal, granulosa cells. It is an immature ovarian follicle. Based on the number of granulosa cell layers, the developing ovarian follicles can be categorised into three classes: primary follicles, secondary follicles, and early tertiary follicles.

So, the correct option is 'Primary follicle'.
