Show answer
Correct Option: C
Explanation:

Prolactin is a hormone secreted in mammals (lactotrophs), usually females and stimulates the mammary gland to produce milk. This hormone is also called luteotropin or luteotropic hormone. The major source of prolactin is the anterior pituitary regulated by the hypothalamus, however, several other tissues synthesize and secrete this hormone. All the other hormones in the options such as hCG, hPL, and estrogen are secreted by the placenta.

Thus, the correct answer is 'Prolactin'.
