The correct answer is:
C

At a given temperature, intensity of radiation emitted increases with the increase of

wavelength, reaches a maximum value at a given wavelength and then starts decreasing with further increase of wavelength. Also, as the temperature increases, maxima of the curve shifts to short wavelength. For Balmer spectral line of H -atom with lowest energy,

and

Where (Rydberg constant)
