Solution
The correct option is C Gastrula The process in which the germ layers are formed during embryonic development is called gastrulation. This stage is characterized by morphogenetic movements such as invagination, ingression, and involution.
In the invagination step, an epithelial lining of cells of the zygote moves inward.
In ingression, cells of the epithelial liningmigrate to form the mesenchymal cells.
In involution, the embryonic tissue undergoes movement and folds inward giving rise to an underlying layer.
