Answer

Correct option: D.
$A$ $B$ $C$
Ovary Glucagon Growth hormone
d
Ovary is the primary female sex organ that produce the female gamete (ovum) and several steroid hormones (ovarian hormone).. Oesetrogens is responsible appearance of female secondary sex characters ($e.g.$, high pitch of voice, etc.) mammary gland development. Oestrogens also regulate female sexual behavior.

Alpha cells of islets of Langerhans of the endocrine pancrease secrete a peptide hormone called glucagon. It plays an important role in maintaining the normal blood glucose levels. It acts mainly on the liver cells (hepatocytes) and stimulates glucogenolysis resulting in an increased blood sugar (hyperglycemia). In addition this hormone stimulates the process of gluconeogensis which also contributes to hyperglycemia. Glucagon reduces the cellular glucose uptake and utilization.Thus, glucagon is a hyperglycemic hormone.
The pars distalis region of pituitary, commonly called anterior pituitary, secretes Growth Hormone $(GH)$, prolactin $(PRL)$, Thyroid stimulating Hormone $(TSH)$, adrenocotrophic Hormone $(ACTH)$, Luteinizing hormone $(LH)$ and follicle stimulating hormone $(FSH)$. Over secretion of $GH$ stimulates abnormal growth of the body leading to gigantism and low secretion of $GH$ results in stunted growth resulting in pituitary dwarfism.
