विकल्प
the scooter has uniform by scooter is the maximum in this section
the distance travelled by scooter is the maximum in this section
the distance travelled by scooter is the minimum in this section
the distance travelled by the scooter is zero in this section

उत्तर
If distance time graph is parallel to the time axis then the object has not travelled any distance. So, the answer is
(d) Distance travelled by the scooter is zero in this section.
