The menstrual cycle starts with the menstrual phase, where the uterus sheds its lining. This is followed by the proliferative phase, where the uterus rebuilds the lining, stimulated by estrogen. Ovulation then occurs, when an egg is released from the ovary. Finally, the progestational phase occurs, where the uterus prepares for potential pregnancy with the release of progesterone. The correct sequence is therefore menstrual phase, proliferative phase, ovulation, and progestational phase, which is represented by choice B.
