Solution

The correct option is B

False


It is true that air around us contains oxygen which supports burning. However, it also contains nitrogen which doesn't support burning but instead controls the extent of burning. Moreover, there is 78% of nitrogen and only 20% oxygen in the atmospheric air. So, even quantity wise nitrogen dominates and doesn't allow excessive burning. Also, for combustion to take place, a fuel as well as sufficient heat energy is required. Of course, in the absence of nitrogen, oxygen would have dominated and everything would have been destroyed by a small fire.
