Answer: D

Explanation:

Recall that the luteal phase of the menstrual cycle occurs after ovulation which occurs after the follicular phase. Progesterone saturation is highest during the luteal phase, and the corpus luteum is most responsible for this increased amount. The oocyte is an egg, which isn’t responsible for progesterone. The ovary is a source of progesterone, but not the primary source. And the corpus callosum is the point of juncture between the hemispheres of the brain.
