    Answer:

    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.

    \lambda_{m}\alpha \frac{1}{T}

    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.
