With reference to the graph, which of the given statement(s) is/are incorrect?
Options:
(a) The instantaneous speed during the interval `t=5s` to `t =10s` is negative at all time instants during the interval.
(b) The velocity and the average velocity for the interval `t=0s` to `t=5s` are equal and positive.
(c) The car changes its direction of motion at `t=5s`.
(d) The instantaneous speed and the instantaneous velocity are positive at all time instants during the interval `t =0s` to `t=5s`.
