The statement does not make sense because (A U B)' can be simplified as A' U B' O B. The statement makes sense because (A U B)' is the complement of the union of sets A and B. O C. The statement makes sense because (A U B) can be simplified as A' U B' () D. The statement does not make sense because (A U B)' is the complement of the union of sets A and B
