Quizplus · Accepted Answer

The neural groove (a) forms first, followed by the approach of the neural folds (b) toward each other. Next, the neural crest cells (c) pinch off from the neural folds. Finally, the neural folds fuse (d) to form the neural tube. Therefore, the correct chronological order for the events is a, b, c, d. Choice C lists the events in the correct order.
