Among the following correct increasing order of energy of subshell’s is

The increasing order of energy of the orbitals depend on both n and l values. If the n+l value is greater for one orbital it has high energy than other orbitals their $n+l$  value is with minimum. Here, the given options both A and B are correct because in these two cases the orbitals are arranged in the increasing order of energy of sub shells according $n+l$  value.
