Solution
The correct option is D corpus luteum Rapid secretion of Leutinizing hormone (LH) results in a hormone surge, causing the Graafian follicle to break. This break releases the ovum, resulting in ovulation. The empty Graafian follicle then turns into a yellow coloured body called corpus luteum which then secretes large amounts of progesterone.
