The electron in a hydrogen atom makes a transition `n_(1) rarr n_(2)` where `n_(1)` and `n_(2)` are the principal qunatum numbers of the two states. Assume the Bohr model to be valid. The frequency of orbital motion of the electron in the initial state is `1//27` of that in the final state. The possible values of `n_(1)` and `n_(2)` are

A

`n_(1) = 4, n _(2) = 2`

B

` n_(1) =3,n_(2) = 1`

C

`n_(1) =8 , n _(2) = 1 `

D

`n_(1)= 6, n _(2)= 3`
