Answer 1

The pituitary gland is divided into two parts: anterior pituitary and posterior pituitary.

Hormones secreted by the anterior pituitary are- Growth Hormone (GH), Thyroid Stimulating Hormone (TSH), Adenocorticotrophic Hormone (ACTH), Prolactin (PRL), Follicle Stimulating Hormone (FSH), Luteinising Hormone (LH).

Hormones secreted by the posterior pituitary are- Oxytocin, Antidiuretic Hormone (ADH)

ACTH, TSH and FSH are secreted by the anterior pituitary whereas ADH is secreted by the posterior pituitary. So, the answer is ADH.
