# s-orbital is spherically symmetricla hence a it is directional independent b angular independent c both (a) and (b) d None of the above

Dear Student,

s-orbital is spherically symmetrical and so it is non-directional i.e. it is independent of direction. It is also angular independent because for s-orbital l=0 which gives m=0. So, the angular wavefunction is constant and so wavefunction of s-orbital depend only on r, i.e. they are radial dependent.
