Among the given mediums, Vaccuum is the best thermal insulator to reduce the transfer of thermal energy by radiation as there will be no air particles which carries heat from one place to other. Hence, Option (D) will be the correct option
<h3>What is Heat radiation ?</h3>
Heat Radiation refers to the transfer of heat from a hot body to cold body directly, without heating the medium between two bodies.
Vaccum does not have any particles in it. Thus, there will be no transfer of heat through it.
The best example of it is thermous flask in which vaccuum inside thermous flask reduces the transfer of energy through it.
