The correct option is C alkyl halides
Carboxylic acids can be prepared by the hydrolysis of acid amides, acid chlorides and acid halides.
RCO−NH2+HOH→R−COOH+NH3
RCO−Cl+HOH→R−COOH+HCl
RCO−X+HOH→R−COOH+HX
Carboxylic acids can not be prepared by the hydrolysis of alkyl halides.
The hydrolysis of alkyl halides gives alcohol.
R−X+HOH→R−OH+HX
