$n=3, l=2, m=1, s=+1/2$

Vedclass · Answer

(C) According to the $(n+l)$ rule,the energy of an orbital increases as the sum of the principal quantum number $(n)$ and the azimuthal quantum number $(l)$ increases.For option $A$: $n+l = 3+0 = 3$For option $B$: $n+l = 3+1 = 4$For option $C$: $n+l = 3+2 = 5$For option $D$: $n+l = 4+0 = 4$Since option $C$ has the highest $(n+l)$ value of $5$,it represents the highest energy state.
