Reaction A is neutron-induced splitting of uranium into two medium-mass nuclei plus neutrons. Hence it is nuclear fission: A–III. Reaction B is ordinary formation of water from hydrogen and oxygen. Hence it is a chemical reaction: B–I. Reaction C combines two deuterons to produce helium-3 and a neutron. This is a fusion reaction with positive Q-value: C–II. Reaction D is the listed fusion process with negative Q-value: D–IV. Therefore the correct matching is A–III, B–I, C–II, D–IV. Correct opti…
