Solution
The correct option is C Uterus
The uterus is single and it is also called as womb. The wall of the uterus has three layers of tissue. The external thin membranous perimetrium, middle thick layer of smooth muscle, myometrium and inner glandular layer is called as endometrium, that lines the uterine cavity. The endometrium undergoes cyclical changes during menstrual cycle, while the myometrium exhibits strong contraction during delivery of the baby. The trophoblast layer of zygote gets attached to the endometrium and the inner cell mass gets differentiated as the embryo. After attachment, the uterine cells divide rapidly and covers the blastocyst. As a result, the blastocyst becomes embedded in the endometrium of the uterus. This is called as implantation and it leads to pregnancy.So, the correct answer is option B.
