Correct Answer: Carbon Monoxide
Solution : The correct option is Carbon Monoxide.
Carbon Monoxide (CO) is the gas that can result from burning coal, or coke in a closed space. Colourless and odourless, carbon monoxide is created when fuels containing carbon, like coal or coke, burn incompletely. A buildup of carbon monoxide can be hazardous in a closed or poorly ventilated space because it can displace oxygen and induce suffocation.
