In an $X$-ray tube, electrons emitted from a filament (cathode) carrying current I hit a target (anode) at a distance $d$ from the cathode. The target is kept at a potential $V$ higher than the cathode resulting in emission of continuous and characteristic $X$-rays. If the filament current $I$ is decreased to $\frac{ I }{2}$, the potential difference $V$ is increased to $2 V$, and the separation distance $d$ is reduced to $\frac{ d }{2}$, then

$(A)$ the cut-off wavelength will reduce to half, and the wavelengths of the characteristic $X$-rays will remain the same

$(B)$ the cut-off wavelength as well as the wavelengths of the characteristic $X$-rays will remain the same

$(C)$ the cut-off wavelength will reduce to half, and the intensities of all the $X$-rays will decrease

$(D)$ the cut-off wavelength will become two times larger, and the intensity of all the $X$-rays will decrease
