The radial function depends upon quantum number n and l whereas angular functions depend upon quantum numbers I and m, i.e., these are independent of n. The total wave function may therefore, be written as \[\psi (r,\,\,\theta ,\,\,\phi )=\,\,\,\underset{(radical\,part)}{\mathop{{{r}_{nl}}}}\,+\,\,\,\underset{(angular\,\,part)}{\mathop{{{\theta }_{l,m}}\,\,{{\phi }_{n}}}}\,\] The number of radial node present in 4d-orbital is

A)  3                                

B)  2

C)  1                                

D)  0
