Two identical objects \( A \) and \( B \) are at temperatures \( T_{A} \) and \( T_{B} \) respectively. Both objects are placed in a room with
\( \mathrm{P} \) perfectly absorbing walls maintained at temperatures \( T \) \( \left(T_{A}TT_{B}\right) \). The objects \( A \) and \( B \) attain temperature \( T \)
W eventually. Which one of the following is correct statement
[CPMT 1997]
(a) 'A' only emits radiations while \( B \) only absorbs them until both attain temperature
(b) A loses more radiations than it absorbs while \( B \) absorbs more radiations that 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 \( T \)
