According to the Standard Model muon is the only elementary particle. All others are composite particles. Pi-Meson consists of 1 quark plus 1 anti-quark, neutron is consisting of 3 quarks, deuteron is a nucleus consisting of 1 proton and 1 neutron, while alpha particle is a neucleus consisting of 2 protons and 2 neutrons.
The binding energy of each nucleon in a heavy nucleus (A~240) is about 7MeV , whereas the binding energy of each nucleon in a medium weight nucleus (A~120) is about 8Mev , therefore when fission occurs the system reduces its internal energy by an amount of 240*1MeV=240 MeV. This amount is liberated from the system in a variety of ways, such as kinetic energy of the two occuring nuclei, kin. energy of neutrons that are emmited, beta and gamma emmision, etc. The greatest percent of this energy is given to the two occuring nuclei, which in a symmetric fission(their A is te same) take about 200 MeV from the energy liberated.
So the correct answer is 200 MeV.
