Answer: (B)

Verified step by step guidance

1. Understand that the brain consists of multiple parts, each with specialized functions related to processing information and controlling bodily functions.
2. Identify the role of the brainstem, which primarily manages basic life functions such as breathing and heart rate, rather than complex information processing.
3. Recognize that the cerebellum is mainly responsible for coordination and balance, not the primary center for processing most information.
4. Know that the thalamus acts as a relay station, transmitting sensory and motor signals to other parts of the brain, but it does not perform the majority of information processing itself.
5. Focus on the cerebral cortex, which is the outer layer of the brain and is responsible for higher-order brain functions such as perception, thought, reasoning, and decision-making, making it the primary area for most information processing.
