{'carbon dioxide iii': [1, 0, 0, 0], 'water vapour ii': [1, 0, 0, 0], 'air': [1, 0, 0, 0], 'hydrogen gas': [0, 0, 1, 2]}
The correct answer is option 2: Only II. Carbon dioxide is considered an air pollutant because it contributes to climate change and global warming. Water vapor, on the other hand, is a natural component of the Earth`s atmosphere and is not considered a pollutant. Hydrogen gas is also not an air pollutant as it is a clean and non-toxic gas. It is important to distinguish between natural components of the atmosphere and pollutants that are harmful to human health and the environment.
