Arrange the orbitals of H-atom in the increasing order of their energy `3p_x`, 2s, `4d_(xy)`, 3s, `4p_z`, `3p_y`, 4s

Options

A. `2s lt 3s = 3p_x = 3p_y lt 4s = 4p_z = 4d_(xy)`
B. `2s lt 3s lt 3p_x = 3p_y lt 4s = 4p_z = 4d_(xy)`
C. `2s lt 3s lt 3p_x = 3p_y lt 4s = 4p_z = 4d_(xy)`
D. `2s lt 3s lt 3p_x = 3p_y lt 4s lt 4p_z lt 4d_(xy)`

Answer

A
