Why should a carbon monoxide detector be used in any room where gas-fired space heaters are being used?

B) High levels of CO can cause nuisance trips of the space heater's oxygen depletion sensor.
C) The efficiency of gas-fired space heaters drops when the CO level in the room exceeds 500 ppm.
D) Gas-fired space heaters can produce carbon monoxide if the space they are operating in does not have adequate combustion air.
