The typical chronological order in which structures appear during neurulation in the anterior region of an amphibian embryo is neural plate, neural folds, deep neural groove, and neural tube. This is because the neural plate folds up and creates the neural folds, which deepen into the deep neural groove, and then fuse together to form the neural tube. Choice B is the only option that follows this order.
