Some laws/processes are given in Column $I$. Match these with the physical phenomena given in Column $II$ and indicate your answer by darkening appropriate bubbles in the $4 \times 4$ matrix given in the $ORS$.

Column $I$ Column $II$
$(A)$ Transition between two atomic energy levels $(p)$ Characteristic $X$-rays
$(B)$ Electron emission from a material $(q)$ Photoelectric effect
$(C)$ Mosley's law $(r)$ Hydrogen spectrum
$(D)$ Change of photon energy into kinetic energy of electrons $(s)$ $\beta$-decay
