A substance from which oxygen is removed undergoes which process?

Answer and explanation

Correct answer: Reduction

Removal of oxygen from a substance is called reduction in the oxygen-based description of redox reactions. For example, copper(II) oxide can lose oxygen and change into copper, so the oxide is reduced. Oxidation is the opposite oxygen change, namely addition of oxygen. Neutralisation concerns acid-base reactions, while displacement concerns replacement of one element by another. Therefore option B is correct.
