(A) When an organic compound is heated with $CuO$,carbon is oxidized to $CO_{2}$ and hydrogen is oxidized to $H_{2}O$. Since the compound produces $CO_{2}$,it must contain carbon. Since it does not produce water,it does not contain hydrogen. Among the given options,$CCl_{4}$ (carbon tetrachloride) is the only compound that contains carbon but no hydrogen. Therefore,the correct option is $A$.
