What part of the brain is responsible for planning and decision making?

• A. Cerebellum
• B. Cerebrum
• C. Brainstem
• D. Hypothalamus

Answer: (B)

Planning and decision making rely on higher cognitive processing housed in the cerebrum, especially the frontal lobes and the prefrontal cortex. This region integrates information from memory, emotion, and sensory inputs to form goals, anticipate outcomes, weigh options, and organize the steps needed to act. The cerebral cortex supports these executive functions, which is why the cerebrum is the best answer for this question.

In contrast, the cerebellum coordinates and fine-tunes movements, the brainstem manages basic life-sustaining functions like breathing and heart rate, and the hypothalamus regulates autonomic and hormonal functions such as hunger, thirst, and temperature. These areas are essential for living and motor control, but they do not handle the higher-level planning and decision-making processes.
