The Graafian follicle ruptures to release the ovum from the ovary by a process called:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Ovulation.
In the ovary, a primary follicle grows step by step into a mature Graafian follicle, which holds the secondary oocyte. In the middle of the menstrual cycle, a sharp rise of luteinising hormone (LH), the LH surge, makes this follicle burst open. The secondary oocyte (ovum) is then released from the ovary. This release of the ovum is called ovulation. It happens at about the 14th day of a 28-day cycle.

Gametogenesis – “… The tertiary follicle further changes into the mature follicle or Graafian follicle (Figure 2.7). The secondary oocyte forms a new membrane called zona pellucida surrounding it. The Graafian follicle now ruptures to release the secondary oocyte (ovum) from the ovary by the process called ovulation.”
