Solution
The correct option is B Oestrogen
Oxytocin is a neuropeptide released by the posterior pituitary.Prolactin is mainly used to produce milk.
GnRH is secreted by the anterior pituitary and it stimulates the secretion of LH and FSH.
If both the ovaries are removed then the blood plasma level of oestrogen will be affected as it is produced by theca interna cells of Graafian follicles. Oestrogen is the hormone which mainly regulates the growth and development of female accessory reproductive organs, secondary sexual characters, and the sexual behavior.So, the correct answer is option C.
