Correct Answer - Option 4 : Carbon monoxide gas may be formed which, if inhaled, is found to be very poisonous.

The correct answer is Carbon monoxide gas may be formed which, if inhaled, is found to be very poisonous.

  • The incomplete combustion of coal releases many poisonous gases like carbon monoxide into the environment.
  • This carbon monoxide gas is fatal to health, can lead to coma and even death of the persons sleeping in that room.
  • This carboxyhemoglobin decreases the oxygen-carrying capacity of blood in our body.
  • Thus the brain gets deprived of oxygen.
  • This leads to suffocation and eventually leads to death.
  • So it is advised not to sleep in a closed room with coal burning inside it.

  • Carbon monoxide is a poisonous gas and causes asphyxiation.
  • Burning coal gives Carbon monoxide and consumes oxygen from the room.
