#### Work Step by Step

The correct answer is:
(d) a car traveling eastward and slowing down
If the car is traveling eastward, then the velocity vector is directed eastward. Since the car is slowing down, the acceleration vector must be in the opposite direction. Therefore, the acceleration vector points in the westward direction.
This car has a westward acceleration.
