The correct answer is:

                    

After fertilization, the zygote forms first (E), followed by cleavage where the cell divides to form , and more cells . This mass of cells is called the morula , which then continues to divide and differentiate into a blastocyst . The final step in this early stage is the implantation of the blastocyst into the uterine wall , which leads to pregnancy.
