The radius of the orbit of an electron in a Hydrogen-like atom is 4.5 a0 where a0 is the Bohr radius. Its orbital angular momentum is 3h/2π . It is given that h is Planck’s constant and R is Rydberg constant. The possible wavelength(s), when the atom de-excites, is (are)
(A) 9/32R
(B) 9/16R
(C) 9/5R
(D) 4/3R
