The reaction has a single reactant.
A decomposition reaction involves one substance breaking down into two or more products (e.g., 2H2O2 → 2H2O + O2). The other options describe different kinds of reactions (oxygen often appears in combustion, ions in ionic/aqueous reactions, a single product suggests synthesis/combination).
