\[\begin{array}{cc}
\phantom{............}\ce{CH3}\\
\phantom{........}|\\
\phantom{}\ce{CH3CH2-C-OH} \\
\phantom{........}|\\\phantom{.............}\ce{CH3}\\

Explanation: 

As tertiary carbocation is more stable, so tertiary alcohols will yield the corresponding alkyl chloride on reaction with concentrated HCl at room temperature.
