Which statement correctly describes the relationship between the electric field and the electric potential along a straight line in space?
(a) The electric field points toward increasing electric potential, and its magnitude equals the rate of change of potential with distance.
(b) The electric field is always perpendicular to the direction in which the potential changes.
(c) The electric field points toward decreasing electric potential, and its magnitude equals the rate of change of potential with distance.
(d) The electric field points toward decreasing electric potential, and its magnitude equals the product of the potential difference and the distance.
