A neutron collides head on with a stationary hydrogen atom in ground state.Which of the following statements is /are true??

a)if kinetic energy of the neutron is less than 13.6eV , collision must be elastic.

b)if kinetic energy of the neutron is less than 13.6eV, collision may be inelastic.

c)Inelastic collision may take place when initial kinetic energy of neutron is greater than 13.6eV.

d)perfectly inelastic collision can not take place.

plz explain!!
