Use indirect truth tables to determine whether each set of propositions is consistent. If the set is consistent, choose an option with a consistent valuation. (There may be other consistent valuations.)
(A ∨ B) ∨ C
~C
~A ⊃ B
(A)Inconsistent (B)Consistent. Consistent valuation when A and B are true and C is false (C)Consistent. Consistent valuation when A and C are true and B is false (D)Consistent. Consistent valuation when B and C are true and A is false
B
