Given below are two statements. In the light of the above statements, choose the correct answer from the options given below.
Statement I:The contrapositive replaces the subject with the complement of the predicate and the predicate with the complement of the subject.
Statement II:All contrapositions are valid.
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 definition of contraposition is right, but not every contraposition is valid.
The contrapositive replaces the subject with the predicate's complement and the predicate with the subject's complement (Statement 1 holds).
For the A proposition full contraposition is valid, and for E it holds only by limitation.
For the I proposition contraposition yields no valid inference at all.
Hence the claim that all contrapositions are valid fails (Statement 2 is false).
