Do Distributions Tell Us the Actual Number of Members in Each

Do distributions tell us the actual number of members in each class, or do they simply tell us the percentage of members in each class?

A) They can either tell us the actual number or the percentage.
B) They can only tell us the percentage, since they involve multiple categories.
C) They can only tell us the percentage, since they are only used when actual counts aren't available.
D) They must always tell us the actual number, since we could never know the percentage in each class without knowing the actual number first.
E) They must always tell us the actual number, since if they only told us the percentage, they would be frequencies rather than distributions.
