FSO2(OH) is fluorosulfuric acid, one of the strongest known superacids. The name combines 'fluoro-' (fluorine attached) with 'sulfuric acid'. Options A and C incorrectly use 'Fluric/Flurous' (misspellings), while option D incorrectly orders the components as 'Sulphur fluric acid' rather than the correct systematic name.
