Which of the following is the characteristic feature of an argument?
AIt is either valid or invalid ✓ Correct
BIt is neither valid nor invalid
CIt is either true or false
DIt is neither true nor false
Correct answer: (A) It is either valid or invalid — An argument is either valid or invalid, so that is the answer.
Explanation
★An argument is either valid or invalid, so that is the answer.
★Validity and invalidity are properties of arguments as a whole.
★Truth and falsity, by contrast, belong to individual propositions.
★So an argument is not itself called true or false.
★It is instead judged as valid or invalid.
★So the characteristic feature of an argument is being valid or invalid.
