(A) In a Coolidge tube,the continuous $X-$ray spectrum is produced due to the deceleration of electrons hitting the target. The energy of the emitted photon $E = h
u$ is derived from the kinetic energy of the incident electrons. The maximum frequency $
u_{\max}$ corresponds to the case where the entire kinetic energy of an electron is converted into a single photon,given by $h
u_{\max} = eV$,where $V$ is the accelerating potential. Since electrons can lose any fraction of their kinetic energy,the frequency $
u$ of the emitted $X-$rays can range from $0$ up to a maximum value $
u_{\max}$. The intensity $I$ is zero at $
u = 0$ and $
u = 
u_{\max}$,and it reaches a peak in between. This corresponds to the graph in option $A$.

The continuous $X-$ray spectrum obtained from a Coolidge tube is of the form:
