Solution

The correct option is A Decrease in estradiol
Estradiol is a female sex hormone and plays a role in the development of female secondary sexual characteristics. It is an estrogen steroid hormone. It has a role in maintaining the lining of the vagina, endometrium and fallopian tubes. However, there is no direct co-relation with the event of ovulation specifically. All the other events mentioned, are involved in the ovulation phase of the menstrual cycle in the human female.
So, the correct answer is 'Decrease in estradiol'.
