Concept:Electric charge is a fundamental property of matter that can be positive or negative.Explanation:Charge is an intrinsic property because every matter naturally possesses an electric charge.Charge is a scalar quantity because it follows algebraic addition, not vector rules.Charge is quantised because the total charge on a body is always an integral multiple of the elementary charge:$$Q = ne$$where $n$ is an integer and $e$ is the charge on an electron.However, charge does not obey the superposition principle.The principle of superposition applies to electric forces and electric fields, not to the charge itself.Therefore, the statement "Charge obeys superposition" is incorrect.Answer:Option D — "Charge obeys superposition" is the incorrect statement.
