The four stages of development of the nervous system are proliferation (the production of new cells), migration (the movement of neurons to their final location), circuit formation (the formation of connections between neurons), and circuit pruning (the elimination of unnecessary connections). Option B correctly represents the order of these stages. Option A is incorrect because innervation comes after proliferation and migration. Option C is incorrect because migration comes before innervation. Option D is incorrect because "cropping" is not a stage of nervous system development.
