Best answer
The correct option is (b) CO2

The best I can explain: Based on molecular weight, 12kg of carbon combines with 32kg of oxygen forming 44kg of carbon dioxide.

              i.e., 12kg of C + 32 kg of O2 => 44kg of CO2

              1kg of C + 8/3kg of O2 => 11/3kg of CO2

              Reaction type: synthesis.
