(B) The reaction of toluene $(C_6H_5CH_3)$ with chromyl chloride $(CrO_2Cl_2)$ in the presence of carbon disulfide $(CS_2)$ followed by hydrolysis is known as the Etard reaction.This reaction specifically oxidizes the methyl group of toluene to a formyl group,resulting in the formation of benzaldehyde $(C_6H_5CHO)$.Therefore,the compound $Z$ is benzaldehyde.
