Answer:

D

Explanation:

It can't be A as nuclei must be positive.

It can't be B as nuclei must contain at least one proton, and no electrons.

Technically C may be true, but the question is asking about the nucleus. Not the electron cloud. Electrons aren't found in the nucleus. Only protons and neutrons.
