Question

The correct sequence in the process of development of human embryo is (A) fertilization—zygote—cleavage—morula—blastula— gastrula (B) fertilization—cleavage—morula—zygote—blastula—gastrula (C) fertilization—zygote—blastula—morula—cleavage—gastrula (D) cleavage—zygote—fertilization—morula—blastula—gastrula

Fusion of male and female gamete produces a zygote. Repeated division of the zygote is called cleavage forming a solid morula. After further division and rearrangement a fluid filled cavity surrounded by blastomeres - blastula is formed. The appearance of germ layers mark the gastrula.
