For an atom or ion having single electron, compare the energies of the following orbitals:
`S_(1)=` a spherically symmetrical orbital having two spherical nodes.
`S_(2)`= an orbital which is double dumb-bell and has no radial node.
`S_(3)`= an orbital with orbital angular momentum zero and three radial nodes.
`S_(4)` = an orbital having one planar and one radial node.

A

`S_(1)=S_(2)=S_(3)=S_(4)`

B

`S_(1)=S_(2)=S_(4) lt S_(3)`

C

`S_(1) gt S_(2) gt S_(3) gt S_(4)`

D

`S_(1) lt S_(4) lt S_(3) lt S_(2)`
