Which can reduce

R\mathrm{COOH}\, \to \,\,R\mathrm{C}{\mathrm{H}_2}\mathrm{OH}

View answer and explanation

Correct option: C

\mathrm{B}{\mathrm{H}_3}/\mathrm{THF/}{\mathrm{H}_3}{\mathrm{O}^ + }

Option C (

\mathrm{B}{\mathrm{H}_3}/\mathrm{THF/}{\mathrm{H}_3}{\mathrm{O}^ + }

) is correct because

BH_3

in THF followed by hydrolysis is a reagent that can reduce carboxylic acids to primary alcohols.
