The radius of the orbit of an electron in a Hydrogen-like atom is 4.5 $$a_0$$, where $$a_0$$ is the bohr radius. Its orbital angular momentum is $$\frac{3h}{2 \pi}$$. It is given that h is Planck constant and R is Rydberg constant. The possible wavelength(s), when the atom de-excites, is (are)

A

$$\frac{9}{32 R}$$

B

$$\frac{9}{16 R}$$

C

$$\frac{9}{5 R}$$

D

$$\frac{4}{3 R}$$
