Why is the electrostatic field inside a conductor zero, despite the dimensions of an atom being of the order of an Angstrom, leading to large electric fields between the protons and electrons?

Options

1. AThe electric fields inside a conductor cancel each other out due to the movement of free electrons.
2. BThe electrostatic field inside a conductor is shielded by the arrangement of atoms within the material.
3. CThe excess charges on the surface of an isolated conductor distribute themselves in such a way that the net el
4. DThe electrostatic field is unable to penetrate the inner structure of a conductor due to the repulsion between
