Quizplus · Accepted Answer

The neural groove forms first (event A), followed by the neural folds approaching one another (event B). Neural crest cells then pinch off from the neural folds (event C), and finally, the neural folds fuse to form the neural tube (event D). Therefore, the correct chronological order is A, B, C, D, which corresponds to choice C.
