Which of the following options BEST supports the idea that the electricity and magnetism are interconnected? (A) Electricity is the phenomenon of electric charges, whether they are stopped or moving.

(B) When a particle is stationary, or stopped, it has an electric field, yet if the charge is moving, it also generates a magnetic field.

(C) Any magnetic particle or object has a "north" and "south" pole, with the directions based on the orientation of the Earth's magnetic field.

(D) Magnetism, like electricity, also has associated units of measurement, such as the tesla (T).

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
