When an infant suckles, which of the following are released:
a. prl
b. oxytocin
c. prl and oxytocin
d. estrogen
e. prl and progesterone

The correct answer is option C, PRL and oxytocin.

Explanation:

Prolactin released by the pituitary gland which is stimulated by the hypothalamus is responsible for the alveoli producing milk. Prolactin hormone rises when an infant suckles. Oxytocin causes small muscles around the alveoli to produce the milk via milk ducts.

Oxytocin travels with the bloodstream to the breast, where it causes contraction of the myoepithelial cells. Prolactin has an important function in maternal behavior. An increase in prolactin levels decreases sex hormone levels.

Thus, the correct answer is option C, PRL and oxytocin.
