Default answer

The correct answer is D.
ETOH is eliminated through zero order kinetics. In this type of elimination, there is a constant amount of drug eliminated by unit time. Therefore, hours 1-2 will have the same amount of ETOH drug elimination as hours 5-6. By contrast, most drugs undergo a first order kinetics and will have a constant percentage of elimination through time.
