Given below are two statements regarding oogenesis. Statement I : The primary follicles get surrounded by more layers of granulosa cells, a theca and shows fluid filled cavity antrum. Now it is called secondary follicle. Statement II : Graafian follicle ruptures to release the secondary oocyte from the ovary by the process called ovulation. In the light of the above statements, choose the correct answer from the opti

Step-by-step solution

Option (4) is the answer because, each primary follicle gets surrounded by more layers of granulosa cells and a new theca and are called secondary follicles. The secondary follicles soon transforms into a tertiary follicle which is characterised by a fluid filled cavity called antrum. The Graafian follicle now ruptures to release the secondary oocyte (ovum) from the ovary by the process called ovulation. So, the statement I is incorrect but statement II is correct.
