Assertion: Energy of the orbitals increases as 1s lt 2s = 2p lt 3s = 3p lt 3d lt 4s =4p =4d =4f lt …… in a hydrogen atom.
Reason:Energy of the electron depends completely on principal quantum number.

B. If both assertion and reason are true but reason is not the correct explanation of the assertion
C. If assertion is true but reason is false
D. If the assertion and reason both are false
