Array

Option : C
Explanation : The square of opposition shown below represents the logical relationships between certain propositions in virtue of their form.

The following hold true:
I. Two propositions are contradictory when the truth of one implies the falsity of the other, and conversely.
2. Two propositions are contrary when they cannot both be true.
3. Two propositions are subcontrary when it is impossible for both to be false.
4. Two propositions stand in the relation of subalternation when the truth of the first (the superaltern) implies the truth of the second (the subaltern), but not conversely.
