Here is a Venn diagram with three sets A, B, and C. Seven (non-intersecting) subsets are labelled with the lowercase letters a, b, c, d, e, f, and z. Each subset includes all the white space up to the first black-line borders, but does not cross any black-line border. u d a b A " Consider each set expression and select all the named subsets included in that set.
