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