Answer 1

Answer:

D. Endometrium

Uterus is composed of three layers of tissues. The outer perimetrium holds uterus in shape. The middle myometrium is responsible for contractions while the innermost endometrium is the layer that holds the egg. During menstruation, the inner layer is shredded off along with the egg and the supplying blood vessels.
