D Correct answer
Explanation

Approximately 0.85 litres (850ml) of blood flows through the brain every minute, representing about 15-20% of cardiac output despite the brain being only 2% of body weight. This high blood flow is essential for meeting the brain's intense metabolic demands. 0.50, 0.63, and 0.75 litres are all underestimates.
