  1. ANSWER: [B]

    Explanation: The cerebellum is the part of the hindbrain that controls posture, balance, and coordination of voluntary movements like walking or picking objects.

    • Reflex actions & impulse transmission → spinal cord and neurons.
    • Blood pressure, breathing, heartbeat, swallowing → medulla oblongata.
    • Thinking, reasoning, memory storage → cerebrum.

    Thus, only posture, balance, and coordination are controlled by the cerebellum.
