Witch would have the least variation A) Weights og 20 year olds B) Weights of 20 year old women C) Weights of adult men D) Weights of all adults

The weights of 20 year old women would most likely be the set with the least variation.

Women and men typically have drastically different weights, and weight differs with age - therefore, the selections with the largest syntax have the greatest range of values. This would be both D, C, and A, with each set becoming more defined in range; however, a gender-age specific syntax is more unique than the other alternatives.
