Select the correct option:
Acid rain is formed due to contribution from the following pair of gases:
oxygen and nitrous oxide
The explanation for correct option C: Acid rain is formed due to the contribution of the following pair of gases Oxygen and nitrous acid. These form acid rain after mixing up with the water in the atmosphere.
The explanation for incorrect option A: These gases are non -toxic and they don't form acid or pollutants in the atmosphere.
The explanation for incorrect option C: The gaseous pollutants from industries contain sulphur and nitrogen, not methane which when emitted into the atmosphere. So this mixture of gas also doesn't form acid rain.
The explanation for incorrect option D: Because carbonic acid is a relatively weak acid, the ability of carbon dioxide alone to generate true “acid rain” is very limited and least Therefore this mixture of gas also doesn't form acid rain.
Concluding Statement: From the above reasons, Option B is the correct answer.
