Given below are two statements. In the light of the above statements, choose the correct answer from the options given below.
Statement I:In classical logic, the universal proposition implies the truth of its corresponding particular proposition.
Statement II:Two propositions that cannot both be true and cannot both be false are called contraries.
ABoth Statement I and Statement II are true
BBoth Statement I and Statement II are false
CStatement I is true but Statement II is false ✓ Correct
DStatement I is false but Statement II is true
Correct answer: (C) Statement I is true but Statement II is false
Explanation
The universal does imply its particular, but the given definition names contradictories, not contraries, so Statement 1 is true and Statement 2 false.
In classical logic A implies I and E implies O by subalternation.
So a true universal guarantees the truth of its corresponding particular.
Contraries can both be false though they cannot both be true.
Propositions that can be neither both true nor both false are contradictories, so the second statement mislabels them.
