Answer:
A. The nucleus contain protons, so it has a positive charge.
Explanation:
Nucleus is the dense core of an atom which contains protons and neutrons.
Protons have positive charge.
Neutrons have no charge.
Electrons are negatively charged.
But electrons are present in the energy level i.e. outside nucleus, that is why a nucleus contains positive charge.
