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.

B. Whether the process of cell differentiation begins early or late.

Explanation:

A is wrong b/c it is referring to characteristics the divide protostomes and deuterostomes, not determinates and indeterminates

B is correct - this is the definition of what makes an organism determinate (cell differentiation begins early) or indeterminate (cell differentiation begins late). Correct on Edmentum.

C is wrong b/c it is referring to cleavage formation, not determinate vs indeterminate

D is wrong b/c it is referring to coelom formation and schizocoelomates and enterocoelomates respectively.
