Answer:
Wave X is moving the fastest.
Explanation:
As we know that the speed of the wave is given as the product of frequency and wavelength
so here we will have

now for wave X

now the speed of this wave is

now for wave Y

now the speed of this wave is

now for wave Z

now the speed of this wave is

So correct answer will be
Wave X is moving the fastest.
