Explanation
Menstrual cycle is the reproductive period or cycle of females , it is a complex cycle controlled by female hormones that cause regular bleeding. In humans the menstrual cycle begins at the onset of puberty i.e., the first time a female bleeds or sheds the lining of the uterus and stops after some time which is known as menopause. Menstrual cycle occurs in primates like humans, monkeys and in some bats and elephants. Hence this is the correct option.
