If ${\lambda }_m$ denotes the wavelength at which the radiative emission from a black body at a temperature T K is maximum, then

• A

  ${\mathrm{\lambda }}_{\mathrm{m}}\propto {\mathrm{T}}^4$

• B

  ${\mathrm{\lambda }}_{\mathrm{m}} \mathrm{is} \mathrm{independent} \mathrm{of} \mathrm{T}$

• C

  ${\mathrm{\lambda }}_{\mathrm{m}} \propto \mathrm{T}$

• D

  ${\mathrm{\lambda }}_{\mathrm{m}} \propto {\mathrm{T}}^{-1}$
