The correct choice is (b) Wein’s law

Best explanation: Wein’s law gives the relationship between wavelength and temperature. Wien’s displacement law is defined as the spectral radiance of black body radiation per unit wavelength. The maximum wavelength can be calculated by dividing Wien’s displacement constant with Temperature.
