The correct answer is the Central Nervous System. This system is composed of the brain and spinal cord, and it serves as the main control center for processing and transmitting information throughout the body. The brain acts as the command center, coordinating actions and reactions to stimuli, while the spinal cord functions as a pathway for signals between the brain and the rest of the body.

Meanwhile, the Peripheral Nervous System includes all the nerves that lie outside the central nervous system, connecting the CNS to limbs and organs. The Autonomic Nervous System, a subset of the peripheral system, controls involuntary bodily functions, such as heart rate and digestion, and is divided into sympathetic and parasympathetic systems. The Somatic Nervous System, another component of the peripheral system, is responsible for voluntary movements and the sensation of touch, pain, and temperature. Understanding the distinction among these systems is crucial because each plays a unique role in how the body functions, but only the Central Nervous System is made up specifically of the brain and spinal cord.
