What are some other purposes of prolactin?

Stimulate growth
Control body temperature
Inhibit ovulation
Regulate heartbeat

The correct answer is: Inhibit ovulation

Prolactin is a hormone primarily responsible for milk production and promoting maternal behaviors in mammals. It is not directly involved in controlling body temperature, regulating heartbeat, or stimulating growth. While prolactin levels may indirectly affect these processes, they are not considered primary purposes of prolactin. Inhibiting ovulation, on the other hand, is a function of prolactin in non-pregnant individuals and is known as the "lactational amenorrhea method." This is a natural form of birth control used by breastfeeding mothers. Therefore, the correct answer is C Inhibit ovulation.
