Solution
The correct option is A Coal
Coal catches fire owing
to natural heating and the fire spreads out over bigger
areas. Fires in coal mines are created from natural burning taking
place either underground or on the surface. 75 % of the fires take
place due to natural fire.
Alongside with carbon
dioxide and carbon monoxide, coal fires emit water vapor, soot, dust
and sulfur dioxide, all of which separate quite quickly but can be a major
problem to limited residents depending on how close they are to
the fire and what the conditions are like at the time.
Thus, the correct option is
B.
