Quizplus · Accepted Answer

When coal is burned completely, it reacts with oxygen to produce carbon dioxide and water. This is a well-known chemical reaction that occurs during the combustion of carbohydrates and hydrocarbons. Option B is incorrect as it suggests that coal produces benzene and toxic volatiles when burned completely.
