Answer 2

The given reaction is considered as reduction reaction

Explanation:

Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

$X^{n+}+ne^-\rightarrow X$

Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

$X\rightarrow X^{n+}+ne^-$

For the given chemical equation:

$O+2e^-\rightarrow O^{2-}$

As the atom is gaining electrons, it is undergoing reduction reaction.
