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.

Answer: 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.
