Answer 1

The correct option is D III, IV, I, II

During oogenesis, the ovary produces primary follicles that mature to secondary follicles, tertiary follicles and finally forms Graafian follicles. The Graafian follicle ruptures to release the ovum from the ovary by the process called ovulation and the remaining parts of the Graafian follicle transform as the corpus luteum.
