Solution

The correct option is A

Sulphur dioxide


Sulphur dioxide is the key compound for the laboratory preparation of sulphuric acid.

2SO2(g)+O2(g)2SO3

SO3+H2OH2SO4

Nitric acid is another compound used for the laboratory preparation of sulphuric acid. S+6HNO36NO2+2H2O+H2SO4

Sulphur dioxide can directly be oxidized to sulphuric acid using nitric acid. So getting to sulphur trioxide is not a mandatory step in laboratory synthesis. Converting sulphur or pyrites into sulphur trioxide is not direct/easy.
