Solution

The correct option is C only specified positive values
The energy liberated when an excited electron returns to its ground state can have only specified positive values which corresponds to the energy difference between excited state and ground state. Such value cannot be negative.

DEFINITION VALID FOR SINGLE ELECTRON SYSTEM:
Ground state: Lowest energy state of any atom or ion is called ground state of the atom. It is n

=

1.
Excited energy (IE): Minimum energy required to move an electron from ground state to n

= \infty

is called ionisation energy of the atom or ion.
Ionisation Potential (I.P): Potential difference through which a free electron must be accelerated from rest, such that its kinetic energy becomes equal to ionisation energy of the atom is called ionisation potential of the atom.
Excitation Energy: Energy required to move an electron from ground state of the atom to any other state of the atom is called excitation energy of that state.
Excitation Potential: Potential difference through which an electron must be accelerated from rest to so that its kinetic energy become equal to excitation energy of any state is called excitation potential of that state.
Binding Energy 'or' Separation Energy: Energy required to move an electron from any state to n=

\infty

is called binding energy of the state.
The wavelength of the photon emitted upon an electronic transition from
