Quizplus · Accepted Answer

Neurulation involves the formation of the notochord and the hollow dorsal nerve cord, which are both part of the developing nervous system. The ectoderm, endoderm, and mesoderm are formed earlier in development during gastrulation. Therefore, option D, which includes the notochord and hollow dorsal nerve cord, is the best choice.
