> the answer is reduction.
The transformation of a carboxylic acid to a primary alcohol is always a reduction reaction.

Answer 1

Concepts and reason

Reduction: Loss of oxygens or addition of hydrogens is called reduction.

Oxidation: Loss of hydrogens or addition of oxygens is called reduction.

Fundamentals

The substance which reduced in a chemical reaction is called as oxidising agent. The examples for oxidising agent are ${\rm{PCC,}}\;{\rm{Cr}}{{\rm{O}}_{\rm{3}}}{\rm{/pyridine,}}\;{\rm{and}}\;{\rm{KMn}}{{\rm{O}}_4}$ .

The substance which oxidised in a chemical reaction is called as a reducing agent. The examples for reducing agent are ${\rm{LiAl}}{{\rm{H}}_{\rm{4}}}{\rm{,}}\;{\rm{NaB}}{{\rm{H}}_{\rm{4}}}$ .

The reaction is,

Ans:

Thus, the transformation from carboxylic acid to alcohol is reduction.
