Albert and Abigail, Who Weigh the Same, Each Consumed the Same

Albert and Abigail, who weigh the same, each consumed the same amount of alcohol. An hour later, Abigail has a higher blood alcohol level. How do researchers explain this difference in blood alcohol levels?

A) Women tend to drink at a different rate than men.
B) Women have less of the stomach enzyme alcohol hydrogenase.
C) There are hormonal differences that directly influence the breakdown of alcohol.
D) Despite the similar weights, women tend to have digestive organs that are somewhat smaller and thus alcohol moves through the system faster.
