The graph shows how the height of the water surface at a point in a harbour varies with time t as waves pass the point. [graph: height against time t, with p marking the height above mean height and q marking the distance between two successive points at mean height] What are p and q?

1. Ap: displacement; q: period
2. Bp: displacement; q: wavelength
3. Cp: amplitude; q: period
4. Dp: amplitude; q: wavelength
