- A is true but R is false.
- A is false but R is true.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is NOT the correct explanation of A.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Phenol is more acidic than ethanol because the conjugate base of phenoxide is more stable than ethoxide due to resonance stabilization in phenoxide.
Thus, the correct answer is Option A.
