Gluons act as exchange particles and are known as gauge bosons. They are involved in the forces within the atom as a strong nuclear force that binds the nucleus. Thus, option D is correct.
What is a strong nuclear force?
A strong nuclear force is a type of interaction that is present inside the atom and involves the nucleus. They bind the quarks to make the neutron and the proton, sub-atomic particles.
The strong nuclear force holds the atomic nucleus together and depends on the spin but not the charge. These forces are due to the interaction between the gluons and are stronger than the chemical bonds. The exchange of the mesons results in nucleons that lead to a strong nuclear force.
Therefore, option D. the gluons are responsible for the strong nuclear forces that bind the nucleus.
