3 well D is a natural source of SO2 - B and C relate to NO2 and are thus incorrect - so we have to choose between natural and industrial sources of SO2 - and to be honest, its tough, but they could justify naural causes because rosting of sulfides i believe can now be controlled via scrubbers and the like.

But fossil fuels contain decomposed remains of organisms. I.e. contains sulfur as it is present in proteins.

Btw, I am pretty sure it's B. I wonder how D is supposed to be the answer. (as in 3)
