Solution

The correct option is B BD
The distance between two consecutive compressions or two consecutive rarefactions is called the wavelength. The points A and E represent the start and end of a wave respectively. Hence, the distance AE equals one wavelength. BD is the distance between one trough and the successive crest which is half of the wavelength ( $\frac{λ}{2}$ ). Similarly, CD represents $\frac{1}{4}$ th of the wavelength and AD represents $\frac{3}{4}$ th of the wavelength.
