Answer: B) Decrease s

explanation: Thermal conductivity of non metallic solid amorphous decrease with increase in temperature as the liquid expand the molecules move aparts. 

At there electronic conductivity is practically non existent and due to increase in phonon conditions, thermal conductivity get increased.
