A reflector that is light in color and smooth.

Reason: "Least energy transfer" here means the least absorption of incoming radiation. Light-colored surfaces have low absorptivity (high reflectivity), and smooth, reflective surfaces reflect incident energy specularly rather than trapping it. By contrast dark and/or rough surfaces absorb more (roughness increases trapping and emissivity). (If you meant conduction or convective transfer instead of radiation, surface contact/air flow could change the answer.)
