Assertion:The `pK_(a)` of acetic acid is lower than that of phenol.
Reason:Phenoxide ion is more resonance stablised.

A

If both assertion and reason are correct and reason is correct explanation for assertion.

B

If both assertion and reason are correct but reason is not correct explanation for assertion.

C

If assertion is correct but reason is incorrect.

D

If assertion and reason are both incorrect.
