Vedclass · Answer

(A) The process of human development begins with fertilization,where the sperm and egg fuse to form a single-celled zygote. Following fertilization,the zygote undergoes a series of rapid mitotic divisions known as cleavage,which increases the number of cells without increasing the total volume. This results in the formation of a solid ball of cells called the morula. The morula then develops into a hollow,fluid-filled structure known as the blastula (or blastocyst in mammals). Finally,the blastula undergoes gastrulation to form the gastrula,which establishes the three primary germ layers. Therefore,the correct sequence is: Fertilization $\rightarrow$ Zygote $\rightarrow$ Cleavage $\rightarrow$ Morula $\rightarrow$ Blastula $\rightarrow$ Gastrula.
