Show answer and explanation

Correct answer: (C) P–III, Q–I, R–II

Explanation

Hydrodesulfurization uses supported cobalt–molybdenum catalysts, P–III. Fluid catalytic cracking relies on acidic zeolite catalysts, Q–I. Catalytic naphtha reforming uses platinum on alumina, R–II. These three standard process–catalyst associations give C.
