Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): ¬p is true.
Reason (R): p → q is true and q is false.
In the light of the above statements, choose the correct answer from the options given below:

  1. Both (A) and (R) are true and (R) is the correct explanation of (A)
  2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A)
  3. (A) is true but (R) is false
  4. (A) is false but (R) is true

Answer (Detailed Solution Below)

The correct answer is : Option 1) Both (A) and (R) are true and (R) is the correct explanation of (A)

Key Points

Given:

  • p → q is true
  • q is false

Apply logical inference:

The implication p → q is logically equivalent to ¬p ∨ q. For p → q to be true when q is false, ¬p must be true. That means p is false.

Therefore:

  • Assertion (A): ¬p is true ✅
  • Reason (R): p → q is true and q is false ⇒ ¬p is true ✅
  • Hence, (R) is the correct explanation of (A)

Correct Answer: Option 1) Both (A) and (R) are true and (R) is the correct explanation of (A)
