Answer:
The correct answer will be option-neural tube, hindbrain, metencephalon,
Explanation:
The development of the brain during the embryogenesis takes place by the formation of a neural tube or the predecessor of the central nervous system.
The neural tube arises from the ectoderm layer of the gastrula where the anterior portion of the neural tube forms the brain.
The neural tube development results in the formation of three sacs filled vesicles in which the fist vesicle forms the forebrain, second forms the midbrain and the third vesicle forms the hindbrain.
Later development process divides the hindbrain into two new portions called metencephalon and myelencephalon where the metencephalon forms the cerebellum portion of the brain.
Thus, the selected order is the correct order.
