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)
