The monochromatic emissive power of a blackbody is given by: Wein's Displacement Law: At any given wavelength, the black body monochromatic emissive power increases with temperature. The wavelength lmax at which is a maximum decreases as the temperature increases.

The primary law governing black body radiation is the Planck Radiation Law, which governs the intensity of radiation emitted by unit surface area into a fixed direction (solid angle) from the black body as a function of wavelength for a fixed temperature.

Wein's law is the accurate answer as only it has something to do with monochromatic or spectra emissive power.

Both Planck's and Wein's law deal with monochromatic (single wavelength) radiation.

If the law relating to black body then it is Planck Radiation law.

Stefan-Boltzmann law is the correct answer.
