Solution

The correct option is B
A-Ovary; B-Glucagon; C-Growth hormone

Oestrogen is secreted by the ovaries. It plays a role in the development of secondary sexual characters in females. Glucagon is secreted by the alpha cells of Islets of Langerhans and helps increase the blood sugar level of the body. Growth hormone (GH) or somatotrophic hormone (STH) is secreted by the anterior lobe of the pituitary gland and helps stimulate growth. Oversecretion of this hormone leads to gigantism.
