Answer 2

Answer:

All options apply

Explanation:

Take for example the following oxidation-reduction reaction:

2 H2  + O2   -> 2 H2O  

Hydrogen is oxidized, then its oxidation number increased (from 0 to +1) and lost electrons.

On the other hand, oxygen is reduced,  that is, its oxidation number decreased (from 0 to -2) and gain the electrons lost by hydrogen.
