The electron in a hydrogen atom jumps back from an excited state to ground state, by emitting a photon of wavelength `lambda_(0) = (16)/(15R)`, where R is Rydbergs's constant. In place of emitting one photon, the electron could come back to ground state by

A

Emitting 3 photons of wavelengths `lambda_1,lambda_2` and `lambda_3` such that `1/lambda_1+1/lambda_2+1/lambda_3="15R"/16`

B

Emitting 2 photons of wavelengths `lambda_1` and `lambda_2` such that `1/lambda_1+1/lambda_2="15R"/16`

C

Emitting 2 photons of wavelengths `lambda_1` and `lambda_2` such that `lambda_1+lambda_2="15R"/16`

D

Emitting 3 photons of wavelengths `lambda_1,lambda_2` and `lambda_3` such that `lambda_1+lambda_2+lambda_3="16"/"15R"`
