(B) According to the $(n+l)$ rule,electrons fill orbitals in order of increasing $(n+l)$ values.For $n=6$:$6s: n+l = 6+0 = 6$$4f: n+l = 4+3 = 7$$5d: n+l = 5+2 = 7$$6p: n+l = 6+1 = 7$Comparing the orbitals with the same $(n+l)$ value,the one with the lower $n$ value fills first.Thus,the order is $6s \to 4f \to 5d \to 6p$,which corresponds to $ns \to (n-2)f \to (n-1)d \to np$.
