A drop in the temperature in the reactor.

Fusion reaction rates depend strongly on temperature (particles must have enough kinetic energy to overcome the Coulomb barrier). Lowering the temperature reduces collision energies and the fusion cross section, so the fusion rate — and thus energy production — falls. The other choices either would increase energy production (more fuel), are irrelevant/hard to decrease output (more neutrons), or refer to fission (splitting nuclei), which is not the primary process in a fusion reactor.
