Answer:
The answer is C. FSH
Explanation:
The development of the follicle in the ovary is caused by the increase in blood levels of the follicle stimulating hormone (FSH). FSH is responsible for regulating the follicular phase of ovulation. It is synthesized and secreted by gonadotropic cells of the anterior part of the pituitary gland. FSH stimulates the production of oocytes and a hormone called estradiol during the first half of the menstrual cycle.
