To determine which statements are true based on the movements of the car depicted in the graph, we need to analyze the sections (P, O, N, M) and their characteristics regarding speed and movement.

  1. Section P - If this section is steeply downward, it would indicate that the car is moving in reverse. If it has a gradual slope, it suggests slower motion. Without the actual graph, we can't ascertain this.

  2. Section O - Generally, a steep upward slope indicates that the car is moving forward at higher speeds. If this matches the description, then it can be considered as the fastest forward speed.

  3. Section N - If this section of the graph is flat, it suggests that the car is stationary (not moving). If it has a slight positive slope, it would indicate constant forward speed.

  4. Section M - If this section shows a less steep slope moving forward compared to other sections, it indicates moving at a slower speed. If it's steep, it indicates faster movement.

Based on general interpretations of graphs of car movements without the actual visual context:

  • Statements that are likely true:
    • B: If Section O indeed shows a steep upward gradient, then it’s true the car shows its fastest forward speed.
    • C: If Section N is flat, it indicates the car is stationary.

Thus, the two true statements would be B and C.
