Solution
The correct option is
A
proton and neutron
The forces that act between the neutron-neutron and proton-proton are the result of the exchange of neutral meson between them.
The forces between neutron and proton is due to the exchange of charged meson between them.
The protons and nuetrons continuosly exchange their nature by absorbing and emitting
π
mesons.
