Which statement correctly distinguishes speed from velocity?
(a) Speed requires both magnitude and direction, while velocity needs only magnitude.
(b) Speed is always greater than velocity because distance is always greater than displacement.
(c) Speed is the rate of change of distance and is a scalar, whereas velocity is the rate of change of displacement and is a vector.
(d) Speed is the rate of change of displacement and is a scalar, whereas velocity is the rate of change of distance and is a vector.
