The process by which primary germinal layers are formed is called A) Blastulation B) Cleavage C) Gastrulation D) Implantation

Correct option:(C)Gastrulation

Solution:

Process in which the germ layers are formed during embryonic development is called gastrulation.
Zygote undergoes cleavage and forms a mass of cells that gets arranged into three layers called germ layers.
These three germ layers are ectoderm, endoderm and mesoderm which further undergo the process of organogenesis giving rise to various organs.
