The correct answer is: B. Very short Subnuclear size
The strong nuclear force is the fourth fundamental force (not including gravity) and is the strongest of the four fundamental forces. It is responsible for holding the nuclei of atoms together. The strong nuclear force is mediated by gluons, which are massless particles that carry the color charge. The strong nuclear force has a very short range, which is why it only affects protons and neutrons, which are located very close to each other in the nucleus of an atom.
The other options are incorrect because:
- Option A is incorrect because the strong nuclear force is not infinite in range.
- Option C is incorrect because the strong nuclear force is not very short Nuclear size. The strong nuclear force has a range of about 10^-15 meters, which is much shorter than the size of a nucleus.
- Option D is incorrect because the strong nuclear force does exist.
