The fundamental quantity of unit electricity is the electrical charge, represented in the SI system by the unit Coulomb (C). It is a property related to the number and arrangement of electrons in an atom or a group of atoms.
The fundamental quantity of unit electricity is the electrical charge. This is represented by the unit Coulomb (C) in the International System of Units (SI). Electrical charge is the property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of charges: positive charge and negative charge. This fundamental property is directly related to the number and arrangement of electrons within an atom or a group of atoms. Option 'b. electrical charge' from your list is therefore the correct answer to this question.
