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.)
~C ⊃ D
D ⊃ C / C
(A)Valid (B)Invalid. Counterexample when C and D are true (C)Invalid. Counterexample when C is true and D is false (D)Invalid. Counterexample when D is true and C is false
