About black body radiation, which one of the following is a $WRONG$ statement?

The graph shows the blackbody radiation curves at temperatures $T_1$ and $T_2$. Which of the following is correct? $(T_2 > T_1)$

The coefficient of absorption $(a)$ and the coefficient of reflection $(r)$ of a thin uniform plate are $0.77$ and $0.17$ respectively. If $250 \ kcal$ of heat is incident on the surface of the plate,the quantity of heat transmitted $(t)$ is: (in $kcal$)

Regarding black body radiation,which one of the following is the $WRONG$ statement?

Heat energy is incident on the surface of a material at the rate of $1000 \ J \ min^{-1}$. If the coefficient of absorption is $0.8$ and the coefficient of reflection is $0.1$,then the amount of heat energy transmitted through the material in $5$ minutes is: (in $J$)
