The amplitude of a wave is the maximum height of the wave above its rest position. In the given figure, it is clear that the amplitude of wave B is larger than that of wave A.
The wavelength of a wave is the distance between two adjacent points that are in phase (e.g. two crests or two troughs). From the figure, it is evident that wave A has a larger wavelength. Therefore, the correct statement is "Wave B has a larger amplitude, and Wave A has a larger wavelength." Hence, the answer is D.
