D Correct answer
Explanation

Cerebrospinal fluid (CSF) acts as a transport medium, exchanging nutrients, oxygen, and waste products between blood vessels in the brain's ventricles and neural tissues. It provides mechanical cushioning, removes metabolic waste, and maintains chemical balance. Meninges are protective membranes, the vertebral column is bone, and aqueous humor is in the eye.
