Vedclass · Answer

(A) The correct statement is $A$. During blastulation,the cells of the blastoderm undergo rearrangement,and the major presumptive and organ-forming areas are segregated into definite regions. Option $B$ is incorrect because the three germinal layers are established during gastrulation,not blastulation. Option $C$ is incorrect because the blastula of a frog is called a coeloblastula,while discoblastula is found in organisms with discoidal cleavage (e.g.,birds). Option $D$ is incorrect because the fluid-filled space in a blastula is called the blastocoel,whereas the archenteron is the primitive gut cavity formed during gastrulation.
