Solution

The correct option is C Slow neutrons strike $_{92} U^{235}$ isotope
The Nuclear fission reaction of Uranium includes the absorption of slow moving neutrons by nucleus of $_{92} U^{235}$ isotope, to generate two fast moving lighter nuclei, and more neutrons. The energy is released in this process.
