Correct answer: D. Beta hydroxy butyrate
- A. Glucose
- B. Fatty acid
- C. Glycerol

After prolonged starvation, the brain adapts to use ketone bodies, especially beta-hydroxybutyrate, reducing its dependence on glucose. Fatty acids do not cross the blood-brain barrier efficiently enough to become the brain's main fuel.
