Answer 1

Burning and combustion are examples of exothermic reactions. They release energy during the process. Along with energy, they release a lot of smoke, and harmful gases like carbon die oxide, nitrogen oxide, sulphur oxide etc.

All these harmful gaseous emissions, smoke and other particulate matter cause pollution of the environment, particularly air pollution.

So the correct option is B.
