B Correct answer
Explanation

Gastrulation is the dynamic process involving critical changes in the embryo, such as differentiation of cells, establishment of the three primary germ layers and transformation of a single walled blastulla into a double walled gastrulla. During involution or emboly, the insinking endodermal cells migrate anteriorwards along the roof of blastocoel and give a new cavity called gastrocoel or archenteron. It represents the future gut cavity. Blastocoel formed during Blastulla stage is filled with an alkaline albuminous fluid secreted by surrounding micromeres.
