Solution

Clemmensen reduction is used to reduce aldehydes or ketones to hydrocarbons using hydrochloric acid and zinc amalgam.

Figure Rosenmund reduction is a reaction where acid chlorides are converted into aldehydes by employing hydrogen gas over palladium poisoned by barium sulphate.

Figure

Wolff Kishner reduction mechanism begins with the formation of a hydrazone anion which then releases the nitrogen atom to form a carbanion. This carbanion then reacts with the water in the system to give a hydrocarbon. Typically, diethylene glycol is used as a solvent for this method.

Figure

Hence, the correct answer is option: 'A'.
