When a Stationary Plutonium-239 Nucleus Decays into a Uranium-235 Nucleus $^{4}_{2}$

When a stationary plutonium-239 nucleus decays into a uranium-235 nucleus plus an alpha particle, the energy released in the process is 5.24 MeV. The following masses are known: $^{4}_{2}$ He: 4.002603 u $^{235}_{92}$ U: 235.043924 u What is the kinetic energy of the $^{235}_{92}$ U nucleus? (1 u = 931.5 MeV/c²)

A) 0.0829 MeV
B) 0.0837 MeV
C) 0.0852 MeV
D) 0.0863 MeV
