What is the name of the endometrium during pregnancy?

Explanation:
During pregnancy, the lining that normally becomes the endometrium undergoes decidualization and is called the decidua. This transformation, driven by progesterone, prepares the lining for embryo implantation and placental development and serves as the maternal component of the placenta. Within the decidua there are regions such as decidua basalis, capsularis, and parietalis, but the general name for the endometrium in pregnancy is decidua. The other options refer either to the non-pregnant endometrium, the muscular layer of the uterus, or a specific region of the decidua rather than the overall name.
