Reduction is defined as

Explanation:
Reduction is the gain of electrons, which lowers the oxidation state of the species accepting those electrons. This is the opposite of oxidation, where electrons are lost and the oxidation state increases. In a redox pair, one species is reduced while the other is oxidized. For example, Cu2+ gaining two electrons becomes Cu, dropping from +2 to 0. The other options describe loss of electrons, an increase in oxidation state, or no change, none of which correspond to reduction.
