Answer

The lining of the uterus to which the embryo implants is called d) Endometrium.

Explanation

The endometrium is the innermost layer of the uterus. During the menstrual cycle, it thickens in preparation for the implantation of a fertilized egg. If pregnancy does not occur, this lining is shed during menstruation. In cases of successful fertilization, the embryo attaches itself to the endometrium, where it can develop into a fetus. The other options, such as coccyx, trophoblast, and yolk plug, refer to different structures or functions that are not directly involved in the implantation process in the uterus.
