A hollow and a solid sphere of same material and identical outer surface under identical condition are heated to the same temperature at the same time (both have same \( e, a \) ) :
(A) In the beginning both will emit equal amount of radiation per unit time
(B) In the beginning both will absorb equal amount of radiation per unit time
(C) Both spheres will have same rate of fall of temperature \( (d T / d t) \)
(D) Both spheres will have equal temperatures at any moment
