Show answer & explanation
Correct answer: B
CONCEPT
In the traditional square of opposition, A and O are contradictories, while E and I are contradictories: when one member of a contradictory pair is false, the other is true.
A and E are contraries, so the falsity of one leaves the other undetermined. Truth descends from A to I and from E to O, while falsity ascends from I to A and from O to E.
APPLICATION
The subalternation A→I carries truth downward, not falsity. If A is false, I remains undetermined; hence A maps to III.
If E is false, its contradictory I is true; hence B maps to IV.
If I is false, its contradictory E is true; hence C maps to II.
If O is false, falsity ascends from O to E, so E is false; hence D maps to I.
CROSS-CHECK / CONTRAST
A-I, B-III, C-II, D-IV treats A being false as forcing E false and leaves I undetermined when E is false; neither follows from the square.
A-II, B-I, C-III, D-IV reverses the contradictory consequences for E and I and does not preserve the upward flow of falsity.
A-IV, B-II, C-III, D-I treats A being false as enough to make I true and E being false as enough to make E true; neither follows.
Therefore, the derived mapping is A-III, B-IV, C-II, D-I.
