(P) $5p_y\to$ (3): It has the highest value of $(n+\ell )=5+1=6$ compared to the other orbitals.

(Q) $3d_{yz}\to$ (1): It has the maximum number of nodal planes (angular nodes = $\ell =2$).

(R) $4s\to$ (4): All $s$-orbitals are spherically symmetrical and completely non-directional.

(S) $2p_z\to$ (2): Chromium ($Z=24$: $[Ar]3d^{5}4s^1$) has a completely filled (fulfilled) $2p$ subshell containing $2p_z^2$.
