Answer:
The correct answer is C. Burning fuel releases carbon monoxide and other chemicals into air.
Explanation:
The burning of flue realeases carbon monooxide which is highly reactive.Carbon monoxide binds with hemoglobin resulting in the formation of carboxy hemoglobin.
Carbon monoxide interacts binds high affinity to hemoglobin than oxygen.The binding of carbon monoxide to hemoglobin displaces the oxygen from hemoglobin thus reducing the affinity of the later for oxygen.
When carbon monoxide binds to hemoblobin, then less hemoglobin is available to bind and transport oxygen to the peripheral tissues of the body..An exposure to carbon monoxide for long period of time can cause death.
