B: carbon dioxide

C: oxygen

Answer 1

Carbon dioxide

Step-by-step explanation:

Fossil fuels usually contains hydrocarbons

While burning they react with oxygen to form carbon dioxide and water .

The reaction is exothermic and given by

• CH_4+O_2—›CO_2+H_2O

Answer 2

Option B, carbon dioxide

Step-by-step explanation:

Step 1: Determine the correct solution

We hear about it all the time, global warming and the reason behind it is all of the carbon emission. Carbon emission is produced by the increase in carbon dioxide that is produced.

`Fuel + O_2 = CO_2 + H_2O`

From this equation we can see that using fuel, it consumes oxygen also, it produces CO2 which is also known as carbon dioxide. Therefore, the correct option is option B.

Answer: Option B, carbon dioxide
