Solution

The correct option is A $C S_{2}$
The solvent used in the formation of benzaldehyde from toluene should be a non-polar solvent for the completion of reaction. Since $C S_{2}$ is a non polar solvent, it is used as a solvent in Etard reaction. Other solvents that can be used are chloroform and carbon tetrachloride.
