Two identical objects $A$ and $B$ are at temperatures $T_A$ and $T_B$ respectively. Both objects are placed in a room with perfectly absorbing walls maintained at temperature $T$ $(T_A > T > T_B)$. The objects $A$ and $B$ attain temperature $T$ eventually. Which one of the following is the correct statement?

  • A
    $A$ only emits radiations while $B$ only absorbs them until both attain temperature $T$.
  • B
    $A$ loses more radiations than it absorbs while $B$ absorbs more radiations than it emits until temperature $T$ is attained.
  • C
    Both $A$ and $B$ only absorb radiations until they attain temperature $T$.
  • D
    Both $A$ and $B$ only emit radiations until they attain temperature $T$.
