b. whether the process of cell differentiation begins early or late.
c. whether the embryonic cells show spiral or radial cleavage.
d. whether the coelom forms by splitting the mesoderm or through the pocket of the gut.

I think the correct answer from the choices listed above is option C. The division for higher invertebrates into determinates or indeterminates is based on the developmental function whether the embryonic cells show spiral or radial cleavage. Hope this answers the question.
