Answer 2

Answer:

Air pollution is caused because of the high proportion of undesirable gas like Sulphur dioxide. Hence, the correct answer will be option C among the other given options.

Explanation:

• Methane is natural gas. It is saturated hydrogen and is absorbed by the plants. Hence, Option A which states, "methane" is the wrong answer to the abovementioned question.
• Hydrogen and Carbon are both natural elements that are present in the air. Hydrogen bonds with oxygen to form water and carbon has it wide range of work. Hence, we can safely eliminate options B and option D.
• Sulphur dioxide is formed when sulfur is burnt in the air. It is extremely toxic and harmful to human beings. It is a poisonous gas present and living can suffer a lot because of it. Hence, it is safe to conclude that option C is the correct answer to the abovementioned question.
