Computer Science20251 markAssertion-reason

Assertion: The expression $\sim ( X \vee Y )$ is logically equivalent to $(\sim X \wedge \sim Y)$

Reason: The commutative property of logical operators states that the order of the operands does not change the result of a binary operation.

Given below are two statements marked, Assertion and Reason. Read the two statements carefully and choose the correct option.
  • (a)Both Assertion and Reason are true and Reason is the correct explanation for Assertion.
  • (b)Both Assertion and Reason are true but Reason is not the correct explanation for Assertion.
  • (c)Assertion is true and Reason is false.
  • (d)Both Assertion and Reason are false.

Correct option: (b)

Answer: (b) Both Assertion and Reason are true but Reason is not the correct explanation for Assertion. Assertion: $\sim(X \vee Y) = (\sim X \wedge \sim Y)$ is true, by De Morgan's law. Reason: the commutative property (order of operands does not change the result of a binary operation) is also a true statement, but it is unrelated to De Morgan's law and does not explain why the Assertion holds.
