Explanation
A. To ensure that the uterus is securely connected to the supporting ligaments: This is not the primary function of the middle layer (myometrium); rather, the supporting ligaments provide stability to the uterus.
B. To allow the uterus to shed tissue during menstruation: This is primarily the function of the endometrium, the inner layer of the uterine wall.
C. To allow the uterus to contract during childbirth to expel the fetus: The middle layer, known as the myometrium, is composed of smooth muscle that contracts during labor to help expel the fetus.
