Decreases with an increase in the speed of the electron.

(C) According to the de Broglie relation,the wavelength $\lambda$ is given by $\lambda = \frac{h}{mv}$,where $h$ is Planck's constant,$m$ is the mass of the electron,and $v$ is its velocity (speed). From this relation,it is clear that $\lambda \propto \frac{1}{v}$. Therefore,as the speed $(v)$ of the electron increases,the wavelength $(\lambda)$ associated with it decreases.
