(B) For electron $A$,$n=3$ and $l=2$,which corresponds to the $3d$ subshell.For electron $B$,$n=3$ and $l=0$,which corresponds to the $3s$ subshell.According to the $(n+l)$ rule,the energy of an orbital increases with the $(n+l)$ value.For $A$,$(n+l) = 3+2 = 5$.For $B$,$(n+l) = 3+0 = 3$.Since the $(n+l)$ value for $A$ is greater than that for $B$,electron $A$ has higher energy than electron $B$.
