In the hydrolysis of esters, all reactants, products as well as Catalysts (H+) are in the aqueous phase and hence it is an example of Homogenous catalysis

In Haber's process, the catalyst is Fe(s)

In the Contact process, the catalyst is V2O5(s)

In Ostwald's process, the catalyst is Pt(s)

In all the above reactions, the reactant(s) and product(s) are gaseous.

Hence, the correct answer is Option (4)
