29. When

{ }^{10} \mathrm{~B}

is bombarded by neutrons, a neutron can be absorbed and an alpha particle (

{ }^{4} \mathrm{He}

) emitted. If the

{ }^{10} \mathrm{~B}

target is stationary, the kinetic energy of the reaction products is equal to the. A) kinetic energy of the incident neutron B) total energy of the incident neutron C) energy equivalent of the mass decrease in the reaction D) energy equivalent of the mass decrease in the reaction plus the kinetic energy of the incident neutron
