(B) The $(n + l)$ rule,also known as the $n+l$ rule or the Madelung rule,is a part of the $Aufbau$ principle. According to the $Aufbau$ principle,electrons fill atomic orbitals in the order of increasing energy,starting from the orbital with the lowest $(n + l)$ value. If two orbitals have the same $(n + l)$ value,the electron enters the orbital with the lower $n$ value.
