(a) gravitational
(c) nuclear

A neutron exerts both the gravitational and nuclear forces on a proton. The gravitational force can be seen between a neutron and a proton. However, its strength is negligible. The nuclear force is exerted only if the interacting particles are neutrons or protons or both. A neutron cannot exert electromagnetic force, because it is a neutral particle.
