A:
This is a standard low energy nuclear reaction, n + p --> d.+ gamma. The gamma ray has about 2.2 MeV worth of energy, equal to the binding energy of the deuterium system. The constituent quarks of the neutron and of the proton pretty much ignore each other and go about their own business. At much, much higher interaction energies the quarks and gluons might come into play and produce other particles such as pi mesons.
