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.
