From earliest to latest, the overall sequence of early development proceeds as follows:
A)gastrulation → organogenesis → cleavage
B)ovulation → gastrulation → fertilization
C)cleavage → gastrulation → organogenesis
D)gastrulation → blastulation → neurulation
E)preformation → morphogenesis → neurulation

Question

Quizplus · Accepted Answer

The correct sequence of early development is cleavage (rapid cell division), followed by gastrulation (formation of three embryonic germ layers), and then organogenesis (differentiation of organs and body structures). Therefore, option C, which lists the sequence as cleavage, gastrulation, and organogenesis, is the best choice. The other options either list the steps in the wrong order or include irrelevant steps.
