Solution

The correct option is B A = 2 B = 1 C = 3 D = 4
Formula for H-like:

$v e l o c i t y, v = \frac{2 π k z e^{2}}{n h}$
$E n e r g y, E = (\frac{- 2 π^{2} m k^{2} e^{4}}{h^{2}}) \frac{z^{2}}{n^{2}}$
$R y d b e r g, R = \frac{2 π^{2} m k^{2} e^{4}}{h^{2}}$
$R a d i u s, r = \frac{h^{2} n^{2}}{4 π^{2} m k z e^{2}}$ .
