Solution

The correct option is D Wien's displacement law
We can analyze the radiation coming from stars and obtain the energy distribution over the wavelengths of radiation emitted by them. The wavelength corresponding to the maximum energy of radiation is related to the temperature of the radiating body by the relation: $λ T = c o n s t$ .
This is Wien's displacement law and can be used to determine the temperature of stars.
