The wave function, `psi_(n), l, m_(l)` is a mathematical function whose value depends upon spherical polar coordinates `(r,theta,phi)` of the electron and characterised by the quantum number `n,l` and `m_(l)`. Here `r` is distance from nucleus, `theta` is colatitude and `phi` is azimuth. In the mathematical functions given in the Table, `Z` is atomic number and `a_(0)` is Bohr radius.
For hydrogen atom, the only CORRECT combination is
A. (I ) (i)(P)
B. (I)(iv)(R)
C. (II)(i)(Q)
D. (I)(i)(S)
