The correct option is C trapped air
A thermal conductor is a material that allows energy in the form of heat, to be transferred within the material, without any movement of the material itself. Eg. Metals.An insulator is a material that does not allow a transfer of electricity or heat. Materials that are poor thermal conductors can also be described as being good thermal insulators. Eg. trapped air
