Which term describes a chemical reaction involving the combination of oxygen with other materials?

• A. Oxidation
• B. Combustion
• C. Reduction
• D. Fermentation

Answer: (A)

Oxidation is the chemical reaction where a substance combines with oxygen or increases its oxidation state. It’s the broad term for oxygen reacting with other materials—think of rust forming on iron or the way fuels oxidize over time. Combustion is a specific, rapid type of oxidation that releases heat and light (a flame). Reduction is the opposite, involving gain of electrons or loss of oxygen, and fermentation is a metabolic process that doesn’t describe reacting with oxygen in the general sense. So for a general reaction with oxygen, oxidation is the best fit.
