C). Hormones control the release of eggs.

Explanation: The menstrual cycle is controlled mostly by hormones: oestrogen and progesterone. These hormones controls the release of eggs from the ovary. The ovary releases an egg when there is a peak in the oestrogen level in the body. The release of egg in a menstrual cycle is known as ovulation. Birth control pills contain two synthetic hormones: oestrogen and progestin. These synthetic hormones maintain a consistent level of the natural hormones produced by the body, and an egg will not be released by the ovary if there is no peak in the oestrogen level, thereby they inhibit the release of egg from the ovary. And fertilization can not occur if no egg is released thus pregnancy is prevented.
