Let A = {2, 4, 6, 8}, B = {6, 7, 8, 9}, and C = {2, 8}. Which of the following statements are true?

(a) {8, 7} ⊆ B                                       (b) {7} ⊆ B ∩ C

(c) (A \B ) ∩ C = {2}                          (d) C \ A = ∅

(e) ∅ ∈ B                                              (f ) A ∩ B ∩ C = 8

(g) B \ A = {2, 4}                                 (h) (B ∪ C) \ A = {7, 9}
