When an atom in a reactant gains electrons, it is reduced. The oxidation number of an atom is a reflection of the number of electrons it has relative to its elemental state. Gaining electrons means that the oxidation number decreases.
Therefore, the correct answer is:
A. Its oxidation number decreases.
Therefore, the correct answer is:
A. Its oxidation number decreases.
