Correct Answer: B. Cushions and protects the CNS ✅

📝 Rationale:

✅ Cerebrospinal fluid (CSF) surrounds the brain and spinal cord, providing cushioning, shock absorption, and protection against injury. It also helps remove waste and maintain a stable environment for the central nervous system (CNS).

Why Other Choices Are Incorrect:

❌ Choice A ("Transmits electrical signals in the brain") → Incorrect because electrical signals in the brain are transmitted by neurons through action potentials, not by cerebrospinal fluid.

❌ Choice C ("Controls voluntary muscle movement") → Incorrect because voluntary muscle movement is controlled by the motor cortex in the cerebrum and carried out via the peripheral nervous system, not CSF.

❌ Choice D ("Regulates heart rate and digestion") → Incorrect because heart rate and digestion are controlled by the autonomic nervous system and the brainstem, not by cerebrospinal fluid.

Correct Answer: B) Cerebellum ✅

Rationale:

✅ The cerebellum is responsible for balance, coordination, and fine motor control. It ensures smooth and precise movements and helps maintain posture and equilibrium.

Why Other Choices Are Incorrect:

❌Choice A ("Cerebrum") → Incorrect because the cerebrum controls higher brain functions such as thinking, memory, and voluntary movements, but it is not primarily responsible for balance.

❌ Choice C ("Brainstem") → Incorrect because the brainstem regulates vital functions such as breathing, heart rate, and reflexes but does not control balance and coordination.
