The correct option is A Hindbrain
The hindbrain includes the cerebellum, the pons and the medulla oblongata, which function collectively to support vital bodily processes. The medulla is joined to the spinal cord and controls unconscious, essential body functions such as breathing, swallowing, blood circulation and muscle tone. Located above the medulla is the pons, which receives information from visual areas to control eye and body movements and also plays a role in controlling patterns of sleep and arousal. Information is relayed from the pons to the cerebellum to control the coordination of muscular movements and maintain equilibrium.
