Answer 2

B)CARBON MONOXIDE

The reason is due to incomplete combustion(lack of air or oxygen during combustion) As well as (CO) carbon monoxide is poisonous gas which affects our lungs heavily.Water is produced but carbon monoxide and carbon is also produced.This results to incomplete combustion.The equation for incomplete combustion given below:

propane + oxygen --> carbon + water

$C_{3}H_{8}+2O_{2}-->3C+4H_{2}O$
