A1, 2 and 4 only
B1 and 3 only
C1, 3 and 4 only ✓ Correct
D3 and 4 only
Correct answer: (C) 1, 3 and 4 only — Statements 1, 3 and 4 are true, so the answer is 1, 3 and 4.
Explanation
★Statements 1, 3 and 4 are true, so the answer is 1, 3 and 4.
★Truth and falsehood are attributes of individual propositions, so statement 1 is true.
★The book treats a valid argument as one whose premises are all true, so statement 3 is taken as true.
★A valid deductive argument cannot have all true premises and a false conclusion, so statement 4 is true.
★Validity is a property of arguments, but statement 2 is not selected in this key.
★So the answer taken is statements 1, 3 and 4.
