Since the ages of 21 members are listed, we can assume that we need to find the best choice(s) for the range of ages among the members. The range is the difference between the highest and lowest age.

By looking at the given options, we can eliminate A, B, and C because they only provide a single age.

Option D provides two ages, which means we can calculate the range. If we assume that the lowest age is 40 and the highest age is 42, the range would be 42-40=2.

Therefore, option D is the best choice as it provides information about the highest and lowest age, which helps us calculate the range.
