Explanation:

• Analyze Option 1: The peripheral nervous system (PNS) consists of nerves that connect the central nervous system (CNS, brain and spinal cord) to the rest of the body (muscles, organs, etc.), transmitting signals between them. This matches the function of PNS.
• Analyze Option 2: The PNS is separate from the CNS; the CNS is made of the brain and spinal cord, while PNS is the other part of the nervous system (not part of CNS). So this is incorrect.
• Analyze Option 3: The corpus callosum carries messages between the two hemispheres of the cerebrum, not the PNS. So this is incorrect.

Answer:

A. It communicates between the central nervous system and the muscles and organs.
