Assertion : Phenol is more reactive than benzene towards electrophilic substitution reaction.
Reason : In the case of phenol, the intermediate carbocation is more resonance stabilised.
If both assertion and reason are true and reason is the correct explanation of assertion.

If assertion is true but reason is false.
If both assertion and reason are false.
Assertion: Cis-2-butene gives meso-2, 3-butanediol with dilute alkaline KMnO4 solution.
Reason : Dilute alkaline KMnO4 solution gives trans addition with alkenes.

C.
If assertion is true but reason is false
Cis-2-butene gives meso-2-3-butanediol with dilute KMnO4 solution because alkaline KMnO4 always gives cis-addition on olefins.
Assertion : The presence of Ag+ enhances the solubility of alkenes in water.
Reason : Alkenes are weakly polar in nature.
