From what i understand the correct option would be A. Clouds

Explanation:

What is a particle consisting of a nucleus surrounded by a cloud of electrons?

The region where an electron is most likely to be is called an orbital. Each orbital can have at most two electrons. Some orbitals, called S orbitals, are shaped like spheres, with the nucleus in the center.

What particle travels around the nucleus?

Protons and neutrons are tightly packed in a small solid sphere called the nucleus of the atom. Around this nucleus is a cloud of electrons. Electrons move about in random motion at different levels around the nucleus depending on their energy.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
