Solution

\[\begin{array}{cc}
\ce{CH3\phantom{..............................}}\ce{CH3\phantom{.............................}}\ce{CH3\phantom{}}\\
|\phantom{..................................}|\phantom{.................................}|\\
\ce{\underset{\text{2-Methylprop-1-ene}}{H3C - C = CH2} +{ HCl} ->[Markovnikov][rule] H3C - C - CH3->[KOH(aq.) Hydrolysis][\triangle] H3C - C - CH3}\\
\ce{(C4H8)}\phantom{...............................}|\phantom{.................................}|\phantom{...}\\
\phantom{..............}\ce{(A)}\phantom{.......................}\ce{\underset{\text{2-Chloro-2-methylpropane (B)}}{Cl}}\phantom{.........}\ce{\underset{\text{2-Hydroxy-2-methylpropane (C4H10O)(C)}}{OH}}\\
\end{array}\]
