The amplitude of a wave is defined as the maximum distance from the rest position (or equilibrium position) to the crest (or trough) of the wave.
To determine the correct answer from the provided options, you would typically look at the highest point (crest) of the wave and the lowest point (trough) in the drawing. The amplitude is half the distance between the crest and trough.
Since I can't see the wave drawing, I can't determine the amplitude directly. Based on your options, you should select "the amplitude cannot be determined" if the drawing does not clearly indicate the crest and trough.
If you can observe the peaks and valleys in the drawing, you could calculate the amplitude and choose from the other numerical options accordingly.
