Given below are two statements. In the light of the above statements, choose the correct answer from the options given below.

Statement I:'No S is P' is contrary to 'All S is P'.

Statement II:'Some S is P' is contrary to 'No S is P'.

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

E is indeed contrary to A, but I and E are contradictories, not contraries, so Statement 1 is true and Statement 2 false.

"No S is P" and "All S is P" are the two universals and cannot both be true, making them contraries.

They can, however, both be false, which fits the contrary relation.

"Some S is P" and "No S is P" are exact opposites in truth value.

Since one must be true and the other false, that pair is contradictory, not contrary.
