Answer

Correct option: A.
$\begin{array}{*{20}{c}}
  {C{H_3}C{H_2}CH - C{H_3}} \\ 
  {\,|} \\ 
  {\,\,\,Cl} 
\end{array}$
a
(a) $2-$chloro butane has a chiral carbon atom, hence only it will show optical activity and will possess two enantiomers (one chiral carbon atom).

$C{H_3}C{H_2} - \mathop {\mathop {\mathop {{C^ \bullet }}\limits_|^| }\limits^H - }\limits_{Cl\;} C{H_3}$
