Show answer & explanation
Correct answer: C
Based on the Square of Opposition in categorical logic:
Contradictories are pairs with opposite truth values, such as E and I. Hence, A matches III.
Contraries are universal propositions that cannot both be true, such as A and E. Hence, B matches I.
Subcontraries are particular propositions that cannot both be false, such as I and O. Hence, C matches IV.
Subalternation links universal propositions with their corresponding particular propositions, such as A and I. Hence, D matches II.
The correct matching sequence is A-III, B-I, C-IV, D-II.
