Cayli must choose one activity from each of the following groups: art, sports, and music. If there are 2 art choices, 3 sports choices, and 4 music choices, how many possible combinations of art, sports, and music choices can Cayli make?
(A) 9
(B) 24
(C) 12
(D) 14
(E) 20
For each of the 2 art choices, Cayli can chose 1 of 3 sports choices and 1 of 4 music choices. So for each of the 2 art choices, Cayli has $3 \times 4=12$ possible combinations of sports and music. Since Cayli has 2 art choices, her total number of choices is $2 \times 12=24$.
