Answer:
Option C
Step-by-step explanation:
Your answer is option C or "thermal conductivity." Thermal conductivity relates to conduction, conduction is when heat transfers from a warm object to a cool object increasing the cooler objects temperature. A common example of material that can conduct heat would be something like metal, metal is able to transfer heat a lot quicker than something like rubber. It's not electrical conductivity because that is materials that are able to conduct electricity. It's not boiling point because that is the temperature that causes different liquids to boil, it's not melting point because that is the temperature that causes different materials to melt.
Hope this helps.
