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.)
T ∨ U
W · T / U
(A)Valid (B)Invalid. Counterexample when T and W are true and U is false (C)Invalid. Counterexample when T is true and W and U are false (D)Invalid. Counterexample when W is true and T and U are false
B
