Answer:

B

Explanation:

a complete wave has one "hill" and one "valley". that is a complete cycle.

and so, after the first hill or valley there is a first rest position.

and then, after the second valley or hill we get to the second test position. and only there the complete wave is finished. and the distance between the first and the second subsequent test position, that is the wavelength.
