C)evaporation.
D)convection.

Question

Quizplus · Accepted Answer

When at rest in a cool indoor environment, the primary means of heat loss is through radiation. This is because radiation is the transfer of heat energy from a warmer object to a cooler one via electromagnetic waves, without the need for any medium to physically move the heat. Therefore, even if one is not touching a cool surface (conduction), sweating (evaporation), or in the path of moving air (convection), they will still lose heat through radiation.
