b. fertilization – cleavage –gastrulation – organ formation – tissue specialization
c. cleavage – fertilization – gastrulation – tissue specialization – organ formation
d. fertilization – cleavage – organ formation – gastrulation – tissue specialization
e. cleavage – fertilization – organ formation – tissue specialization – gastrulation

Respuesta :

fertilization comes first
it is followed by cleavage which is the rapid cellular division which forms the blastula
