(D) The reaction of alcohols with hydrogen halides $(HX)$ follows the order: $3^{\circ} > 2^{\circ} > 1^{\circ}$ alcohols.This is because the reaction proceeds via the formation of a carbocation intermediate,and the stability of the carbocation follows the order: $3^{\circ} > 2^{\circ} > 1^{\circ}$.$2$-methyl propane-$2$-ol is a tertiary $(3^{\circ})$ alcohol,which forms a stable tertiary carbocation,making it the most reactive towards $HBr$.
