Answer 1

Answer:A. Being parked too close to a fire engine that is also running.

Step-by-step explanation:

How is carbon monoxide produced?

If wood,gas,oil,coal do not burn completely then carbon monoxide get produced.

In a poorly ventilated area where there is fire the oxygen is slowly exhausted until there is only carbon dioxide left in the room. As carbon builds up within the atmosphere of the room,the fuel doesn't get burnt completely and end up releasing carbon monoxide
