light, carbon dioxide, and water
light and oxygen
oxygen and carbon dioxide
oxygen and water

Explanation:

Step1: Recall combustion reaction basics

Combustion reactions involve a substance reacting with oxygen.

Step2: Analyze products

For example, in the combustion of a hydrocarbon like methane ($\ce{CH4 + 2O2->CO2 + 2H2O + heat + light}$), carbon dioxide ($\ce{CO2}$), water ($\ce{H2O}$), and light (along with heat, though heat isn't in the options here) are produced. Oxygen is a reactant, not a product. So the correct products among the options are light, carbon dioxide, and water.

Answer:

light, carbon dioxide, and water
