option (B) decreases
Explanation:
According to the Wein's displacement law, the minimum wavelength of the radiated emission is inversely proportional to the absolute temperature of the body which emits radiation.
Where, T is the absolute temperature of the body and λm is the minimum wavelength of heat radiated.
Here, as the temperature increases, the wavelength decreases.
