Structure of Atom · Orbital energy n plus l rule

Arrange the following atomic orbitals of multi electron atoms in order of increasing energy.
  • (A)n=3n = 3, ℓ=2\ell = 2, m=+1m = +1
  • (B)n=4n = 4, ℓ=0\ell = 0, m=0m = 0
  • (C)n=6n = 6, ℓ=1\ell = 1, m=0m = 0
  • (D)n=5n = 5, ℓ=1\ell = 1, m=+1m = +1
  • (E)n=2n = 2, ℓ=1\ell = 1, m=+1m = +1
Choose the correct answer from the options given below :
  1. (1)C << D << B << A << E
  2. (2)B << A << E << C << D
  3. (3)E << C << D << B << A
  4. (4)E << B << A << D << C
