The correct option is B CO2
∙ Burning of any substance in the presence of oxygen is called combustion.
∙ When carbon compounds undergo combustion in excess air, they also produce carbon dioxide (CO2) and water (H2O).
∙ During combustion, a lot of heat energy is released along with light.
Hence, the reaction will be:
CH3CH2OH(aq)+3 O2(g)→2 CO2(g)+3 H2O(aq)
