The correct answer is "sexual intercourse" because the other terms listed (venere/o, gynec/o, rectum, and egg) do not directly relate to the concept of sexual intercourse. Venere/o refers to Venus, the Roman goddess of love, and is often used in medical terminology to indicate a sexually transmitted disease. Gynec/o relates to the female reproductive system, rectum refers to the lower part of the digestive system, and egg refers to the female reproductive cell. Therefore, "sexual intercourse" is the only option that directly relates to the given terms.
