Answer:

C

Explanation:

inertia

inertia is the reluctance of an object at rest or moving to change its state of rest or motion

because the car was moving, the dummy moves with the speed of the car..so when the crash happened the dummy continued to move..it was feeling reluctant to come to rest so was moving
