Vedclass · Accepted Answer

If two orbitals have the same value for $(n + \ell)$,then the orbital with the higher value of $n$ will have lower energy.

Vedclass · Answer

(D) According to the $(n + \ell)$ rule: $1$. The orbital with the lower $(n + \ell)$ value has lower energy. $2$. If two orbitals have the same $(n + \ell)$ value,the one with the lower $n$ value has lower energy. Statement $D$ is incorrect because if $(n + \ell)$ is the same,the orbital with the higher $n$ value has higher energy,not lower energy. Statement $B$ is also technically incorrect in a multi-electron system as energy depends on $Z_{eff}$,but $D$ is a direct violation of the Aufbau principle rule.
