I don’t see the answer choices — please paste them if you want me to pick one. Meanwhile, here are the rules to use when reading graphs so you can choose the correct option:

- On a velocity vs. time graph: acceleration is the slope (rise/run).
- Constant positive acceleration → straight line with positive slope.
- Constant zero acceleration → horizontal line (velocity constant).
- Constant negative acceleration → straight line with negative slope.

- On a position vs. time graph: acceleration shows up as curvature (concavity).
- If the position curve is concave up (curves upward), acceleration is positive.
- If concave down, acceleration is negative.
- A straight line position vs. time means zero acceleration.

- On an acceleration vs. time graph: the plotted value is acceleration directly; the area under the curve gives change in velocity.

- Instantaneous acceleration = derivative of velocity with respect to time (a = dv/dt) = second derivative of position (a = d^2x/dt^2). Units: m/s^2.

If you paste the choices, I’ll identify which one best represents acceleration.
