In a square of opposition of propositions, which of the following is correct?

AIf A is given as false, O is undetermined

BIf E is given as false, I is false

CIf I is given as false, A is false ✓ Correct

DIf O is given as false, E is true

Correct answer: (C) If I is given as false, A is false

Explanation

If I is false, then A must also be false.

A and I stand in the relation of subalternation, with A implying I.

Whenever the superaltern A is true, the subaltern I is true as well.

By contraposition, the falsity of I forces the falsity of A.

This follows directly from the square of opposition.
