Correct Answer: Bad absorber, and good reflector of heat


Solution : The correct answer is a Bad absorber and a good reflector of heat.

White and smooth surfaces are bad absorbers and good reflectors of heat. All shiny surfaces are the best reflectors of heat radiation. When the heat radiation falls on the shiny or white surfaces, most of the heat radiations are reflected. Black surfaces are the best absorbers of heat.
