Correct answer

C. Gatterman-koch reaction

Step-by-step solution

Gattermann – Koch reaction is used for the industrial production of benzaldehyde. In Gattermann – Koch reaction, benzene is treated with carbon monoxide in the acidic medium in presence of anhydrous aluminium chloride to give benzaldehyde.
