Solution

The correct option is A Decrease in oestradiol
At ovulation, usually around Day 12 – 14, increased estrogen levels (majorly oestradiol) trigger a sharp rise in Luteinizing Hormone (LH) from the pituitary gland, causing the release of the egg from the follicle. The ruptured follicle (corpus luteum) now secretes progesterone and estrogen to continue to prepare the uterus for pregnancy.
So, the correct option is 'Decrease in oestradiol'
