Solution

The correct option is B Homogeneous catalysis
Homogeneous catalysis: It is defined as, when both reactant and catalyst are in same phase, that is either liquid or gas.
$2 S O_{2} (g) + O_{2} (g) N O (g) ⟶ 2 S O_{3} (g)$ in this reaction both reactants and catalyst are in gaseous phase hence, it is an example of homogeneous catalysis.
