In a laboratory experiment with three groups of students, one group drinks pure water, a second group drinks an equal amount of beer, and a third group drinks an equal amount of concentrated salt solution, all during the same time period. Their urine production is monitored for several hours. Which groups are expected to have the greatest and least amounts of urine, respectively?
A) Beer drinkers have the most; salt solution drinkers have the least.
B) Salt solution drinkers have the most; water drinkers have the least.
C) Water drinkers have the most; beer drinkers have the least.
D) Beer drinkers have the most; water drinkers have the least.
E) There will be no significant difference between these groups.
