C : " Neutrons are inside the nucleus of an atom" is the answer because, Rutherford  theorized if the neutrons were in the center and the electrons were orbiting in separate energy levels the protons would be in the nucleus to keep the neutrons from floating. If the nucleus has neutral and positive particles, then it will be positive nucleus. Hope this helps

The discovery that added to Rutherford's discovery of a positive nucleus is neutrons are inside the nucleus of an atom.

Rutherford, through his ground breaking experiment with a thin gold foil was able to show that the nucleus is composed of a positively charged core called the nucleus.

In addition to this discovery, Chadwick in 1932 discovered the neutrons which are neutral particles but are also contained in the nucleus. They contribute to the mass of the atom.
