Construct a complete truth table for the following argument. Then, using the truth table, determine whether the argument is valid or invalid. If the argument is invalid, choose an option which presents a counterexample. (There may be other counterexamples as well.)
~A · ~B
(A ∨ C) ∨ B / C
(A)Valid (B)Invalid. Counterexample when A and B are true and C is false (C)Invalid. Counterexample when A is true and B and C are false (D)Invalid. Counterexample when B is true and A and C are false
