A (8, 8, 8, 9, 9, 10, 11, 12) B (12, 11, 10, 9, 8} a. Are the sets equivalent? Explain. OA. The sets are equivalent because n(A) = n(B). OB. The sets are equivalent because set A does not contain the exact same elements as set B. OC. The sets are not equivalent because n(A) *n(B). OD. The sets are not equivalent because set A does not contain the exact same elements as set B. b. Are the sets equal? Explain. OA. The sets are not equal because set A contains the exact same elements as set B. OB. The sets are equal because n(A) = n(B). OC. The sets are equal because set A contains the exact same elements as set B. OD. The sets are not equal because n(A) #n(B).
