Three bodies \( \mathrm{A}, \mathrm{B} \) and \( \mathrm{C} \) have equal area which are painted red, yellow and black respectively. If they are at same temperature, then
(a) emissive power of \( \mathrm{A} \) is maximum.
(b) emissive power of \( \mathrm{B} \) is maximum.
(c) emissive power of \( \mathrm{C} \) is maximum.
(d) emissive power of \( \mathrm{A}, \mathrm{B} \) and \( \mathrm{C} \) are equal.
