Which one of the following statements is always correct for the motion of a particle along a straight line?
(a) The distance travelled can be negative if the particle moves opposite to the chosen direction.
(b) For motion along a straight line, the distance travelled and the magnitude of displacement are always equal because the path is a straight line.
(c) The distance travelled is always greater than or equal to the magnitude of the displacement.
(d) The distance travelled equals the magnitude of displacement only when the particle moves with uniform velocity.
