The correct answer is: wavelength corresponding to maximum energy and temperature
Using Wein's displacement law : the wavelength corresponding to maximum energy is inversely proportional to the abolute temperature of the body. i.e.
$\lambda_m \propto \frac{d}{T} \Rightarrow \lambda_m T=\text { constant }$
