Answer:
The correct option is: a. PIH
Explanation:
The PRH or the prolactin-releasing hormone is the hormone responsible for stimulating the release of prolactin from the anterior pituitary gland. Prolactin then stimulates the mammary glands of the mammals, usually females, to produce milk.
The PIH or the prolactin-inhibiting hormone, also known as dopamine, inhibits the production of prolactin and thus blocks the milk formation in males and non-pregnant females.
