Solution
The correct option is B Oestrogen
The ovary is a reproductive organ, found in pairs as part of the vertebrate reproductive system in females. Ovaries are gonads and are endocrine glands. They secrete the hormone oestrogen and in less quantity, testosterone and progesterone. Oestrogen is responsible for the appearance of secondary sex characteristics for females at puberty. So, if both the ovaries are removed, then there will be no production of oestrogen.
Thus, the correct answer is the option (B).
