The correct answer is (b) electrons tightly bound to its atoms.
An electrical insulator is a material that does not allow the flow of electric current easily. This is because the electrons in an insulator are tightly bound to their atoms and are not free to move around like in conductors. As a result, insulators do not conduct electricity well.
To determine the correct answer, we can eliminate options (a) and (c) since they both describe conductors and not insulators. In conductors, the electrons can freely move, either as negatively charged ions or as mobile electrons.
Option (d) is also incorrect because having more protons than electrons would result in a positive charge, which is not typically a characteristic of insulators.
Therefore, option (b) remains as the correct answer, as insulators have electrons tightly bound to their atoms.
