D Correct answer
Explanation

Sulfuric acid is manufactured by the Contact process, which involves catalytic oxidation of SO2 to SO3 over vanadium pentoxide catalyst, followed by absorption in concentrated H2SO4 to form oleum. The name 'Contact' refers to the solid catalyst that 'contacts' the reacting gases. The other options (explosive, emission, fission, chain) are not related to H2SO4 manufacturing.
