Answer:

Reduction

Step-by-step explanation:

Oxidation is a process that involves loss of electrons.

Reduction is a process that involves gain of electrons.

In this equation, the electrons (4e-) are in the reactant side. This means that it is gain of electrons.

The reaction is a reduction reaction.
