Answer
To determine the direction of the resultant force, we first need to calculate it. The driving force is 800 N to the left, and the drag force is 450 N to the right. The resultant force can be calculated as:
Thus, the resultant force is acting to the left, so the correct choice is B to the left (←).

Answer
Since there is a resultant force acting on the car (350 N to the left), according to Newton's second law of motion, this implies the car is accelerating. Therefore, the correct choice is A accelerating.
