Assertion: Commercially carboxylic acids are reduced to alcohols by converting them to the esters followed by their reduction using catalytic hydrogenation.
Reason: `LiAlH_4` can also reduce.carboxylic acids to primary, alcohols but `LiAlH_4` is an expensive reagent and used for preparing special chemicals only

Answer

B

Explanation

Carboxylic acids are reduced to the primary alcohols in excellent yields by lithium aluminium hydride.
But it is not used in the cornmercial production of alcohols because `LiAlH_4` is an expensive reagent.
