Which of the following is a common source of carbon monoxide?

Carbon monoxide is a colorless, odorless gas that can pose serious health risks due to its ability to bind with hemoglobin in the blood, reducing the blood's oxygen-carrying capacity. A primary source of carbon monoxide is combustion processes, which occur in various forms of fuel-burning appliances. Stoves, particularly those that burn gas or other fossil fuels, can produce carbon monoxide if they are not functioning properly or if ventilation is inadequate.

In contrast, solar panels, fluorescent lights, and wind turbines do not rely on combustion and therefore do not emit carbon monoxide during their normal operation. These alternatives are designed to harness energy from sources like sunlight or wind, which do not generate harmful emissions, making them cleaner options compared to traditional fuel-based appliances. Thus, stoves, which can emit carbon monoxide as a byproduct of burning fuel, are recognized as a common source of this dangerous gas.
