Which statement best describes the uterus?

• A. A gland producing milk.
• B. A muscular sac storing urine.
• C. A hollow muscular organ in the pelvic cavity of the female, in which the embryo is nourished and develops before birth; consists of uterine horns and uterine body.
• D. The passageway for eggs.

Answer: (C)

The uterus is a hollow, muscular organ in the female reproductive system where a developing embryo grows and is nourished during pregnancy. In many mammals it has a body and paired uterine horns, all housed in the pelvic cavity. This description matches the structure and function of the uterus, including its anatomical makeup. The other options describe different organs: a gland that produces milk is the mammary gland, a muscular sac storing urine is the bladder, and the passageway for eggs is the oviduct (fallopian tube), not the uterus.
