Which of the following carbocation wouldhave the greatest stability?

Phenoxide ion on treatment with active alkyl halide (e.g., $CH _{2}= CH - CH _{2} Cl$ ) gives two products viz. $O$-substituted and $C$-substituted. Phenoxide ion is an ambident nucleophile.

$S _{ N } 1$ reaction is basically a solvolysis reaction. Polar protic solvents help the substrate to ionise and by the way get involved in $S _{ N } 1$ reaction.
