A) It produces the poisonous gas carbon monoxide
B) Burning consumes all the oxygen and breathing becomes difficult
C) The amount of heal produced is intolerable
D) There is serious risk of fire
Correct Answer: A
Solution :[a] As the charcoal burns, the concentration of carbon monoxide gradually increases. Because of its toxicity (and not the exhaustion of oxygen as sometimes thought) CO concentrations of as little as one part per thousand in the air in a confined space are fatal if inhaled over an extended period. The incomplete combustion of carbon produces carbon monoxide, which binds strongly to haemoglobin, rapidly decreasing the ability of blood to deliver oxygen to the body. This results in death due to hypoxia brought about by carbon monoxide poisoning. Charcoal-burning suicide is committing suicide by burning charcoal in a closed room. It has similarities with the inert gas asphyxiation method of suicide.
