Which one of the following is a true statement with reference to reaction between 2- Bromo-2-methylpropane and aqueous KOH ?

The rate of reaction depends on the concentration of the haloalkane and the nucleophile $\mathrm{OH}^{-}$

The reaction occurs at a fast rate since the substrate is a tertiary alkyl halide and follows $\mathrm{S}_{\mathrm{N}} 1$ mechanism.

The reaction is not favoured by the presence of polar protic solvent.

The reaction occurs at a slow rate since it follows $\mathrm{S}_{\mathrm{N}} 2$ mechanism.
