Which statement about brain function is accurate?

• A. The spinal cord sends signals between brain and body.
• B. The brain controls breathing.
• C. The brain processes information to coordinate bodily functions.
• D. The brain regulates digestion.

Answer: (C)

The brain’s main job is to process information from senses and internal signals and then coordinate the body's actions. This processing links perception, memory, and context to produce organized responses—movements, reflexes, and the regulation of organs. That’s why the statement that the brain processes information to coordinate bodily functions is the most accurate: it captures how the brain integrates what we experience with how our body acts. The other ideas describe parts of a system rather than the brain’s integrative role. The spinal cord is a major communication pathway between brain and body, but focusing on it describes a route rather than the brain’s coordinating function. Breathing is managed automatically by the brainstem, a specific brain region, so stating the brain in general controls breathing is too broad. Digestion is largely governed by the autonomic nervous system and gut processes, with brain influence, but it isn’t a direct sole regulation by the brain.
