The correct option is (c) In the emission spectrum, transition takes place with the absorption of a photon of energy hν

To explain: In the emission spectrum, transition takes place with the emission of a photon of energy hν. All the other options are correct. Emission spectrum results when an electron in an atom undergoes a transition from excited state to the ground state.
