The correct answer is:
$\lambda_m \propto T^{-1}$
According to Wein's displacement law
$$
\begin{aligned}
\lambda_m T & =\text { constant } \\
\Rightarrow \quad \lambda_n & \propto T^{-1}
\end{aligned}
$$
$$
\begin{aligned}
\lambda_m T & =\text { constant } \\
\Rightarrow \quad \lambda_n & \propto T^{-1}
\end{aligned}
$$
