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.)
M ∨ N
~M · O / N
(A)Valid (B)Invalid. Counterexample when M and O are true and N is false (C)Invalid. Counterexample when M is true and O and N are false (D)Invalid. Counterexample when O is true and M and N are false
