Given below are two statements: Assertion (A) and Reason (R).
Assertion (A): ¬p
Reason (R): (r → ¬q, r ∨ s, s → ¬q, p → q)
In the light of the above statements, choose the correct answer.
Pick an option to check yourself, or open the answer below.
Show answer & explanation
Correct answer: A. Both (A) and (R) are true and (R) is the correct explanation of (A)
Explanation
From r ∨ s, r → ¬q and s → ¬q we get ¬q (constructive dilemma). With p → q, modus tollens gives ¬p. The premises in R are exactly what derive A, so R explains A.More Discrete Structures and Optimization questions
