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.)
J ≡ ~K
J ∨ L
~K / L
(A)Valid (B)Invalid. Counterexample when J and K are true and L is false (C)Invalid. Counterexample when J is true and K and L are false (D)Invalid. Counterexample when K is true and J and L are false
C
