Answer:
C) Rear
Explanation:
For better understanding, let me explain first what actually is the Whiplash injury. It usually occurs in the accidents related to vehicles and cause injury in the neck. It happens because of the very forceful, rapid movement of head and neck forward and backward. So unfortunately if there is a sudden impact of car from the rear and if it's velocity changes from 10 to 15 km/h (as the studies show) it will results in the whiplash injuries. So the correct option here is the third one "rear".
