D Correct answer
Explanation

Sulphur dioxide (SO2) is the primary gas emitted from power stations burning coal or oil that reacts with atmospheric water to form sulphuric acid, the main component of acid rain. Nitrogen oxides also contribute, but SO2 from sulphur-containing fossil fuels is the dominant cause of acid rain from power generation.
