Answer:
C. the follicle develops into a hormone-producing structure called corpus luteum
Step-by-step explanation:
The luteal phase is one of the three phases of the menstrual cycle in females (the other being follicular and ovulatory phases). In the luteal phase, which occurs after the egg has been released, the follicle develops into a hormone-producing structure called CORPUS LUTEUM.
Corpus luteum is responsible for producing progesterone hormone, which prepares the uterus for pregnancy. In other words, during the luteal phase, the female reproductive system is preparing itself for another possibility of pregnancy, characterized by the formation of the structure that produces the pregnancy hormone.
