For proposition , its contrapositive is

Computer Science20241 markAssertion-reason

Assertion: For proposition $\sim A \Rightarrow B$, its contrapositive is $B \Rightarrow \sim A$

Reason: Contrapositive is the converse of inverse for any proposition.

  • (a)Both Assertion and Reason are true, and Reason is the correct explanation for the Assertion.
  • (b)Both Assertion and Reason are true, but Reason is not the correct explanation for the Assertion.
  • (c)Assertion is true but Reason is false.
  • (d)Assertion is false but Reason is true.

Correct option: (d)

The Assertion is false: the contrapositive of $\sim A \Rightarrow B$ is $\sim B \Rightarrow A$, not $B \Rightarrow \sim A$. The Reason is true: the contrapositive of a proposition is indeed the converse of its inverse, in general. Since the Assertion is false, the Reason cannot be its explanation. Answer: (d)
