A chemical reaction that has the general formula of AB + C → CB + A is best classified as a synthesis
polymerization
decomposition
oxidation
replacement
reaction.

Replacement  reaction.

Given

A chemical reaction

AB + C → CB + A

Required

reaction type

Solution

There are several types of reactions that can occur

synthesis: 2 elements combine to form a single product

polymerization: monomers combine to produce a polymer

decomposition: One compound breaks down into 2 components

oxidation : a change in oxidation number

replacement can be divided into 2

single replacement if one element replaces the other elements of a compound

double replacement if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds

AB + C → CB + A

If we look at this reaction, element C replaces element A to form a new compound CB. So it is single replacement. But this reaction can also be said to be an oxidation-reduction reaction because there is a change in oxidation number

element A undergoes a reduction reaction

element C undergoes an oxidation reaction

So types of redox reactions can be combination, decomposition, displacement, combustion, and disproportion.
