Solution:
(i) Rohan feels jerk on application of sudden brakes could be explained on the basis of Newton's first law of motion. Option a is correct
Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
(ii)
Option c is correct
(iii) The car slows down with brakes application, but our body remains to continue in the same state of motion because of its inertia.
