4. For a particular statement P→ Q we know that if P = true and Q = true the statement is true. When P = true and Q = false the statement is false. Anytime P = false we know that the statement is inevitably true. How can we best describe these last two "T" truth values in our truth table for P→ Q? (a) The statement is true when P = false because Q = true so the single truth value makes the whole statement true. (b) The statement is true when P = false because Q = false so the single truth value makes the whole statement true. (c) The statement is true when P = false because for whatever value of Q, the statement cannot be proved or unproved. Therefore it is true by default. (d) None of the above
