Two deuterons undergo fusion ²H+²H→³He+n with negligible initial kinetic energy. Total binding energies of ²H and ³He are 2.22 MeV and 7.72 MeV. Neglect photon emission and use final mass ratio m(³He):m(n)=3:1. The neutron kinetic energy is:

1. A

   0.82 MeV

2. B

   2.46 MeV

3. C

   3.28 MeV

4. D

   4.44 MeV
