Solution
The correct option is A A - Ovary, B - Glucagon, C - Growth hormone
The primary function of the ovary is the production of ova. In addition to it, ovary acts like an endocrine organ where it secretes oestrogen, progesterone under the influence of FSH. Oestrogen helps to develop and maintain the secondary sexual characters. Glucagon is secreted by alpha cells of islets of Langerhans which helps to maintain the glucose level by preventing glucose level from falling too low. The pituitary is the master gland of the body which controls the function of various other glands. It is divided into two lobes anterior and posterior. The posterior lobe secretes growth hormone, oversecretion of this hormone leads to gigantism and is mostly caused by a tumor in the gland. It results in the oversecretion of growth hormone. Thus the correct answer is option B.
