Best answer
Right option is (a) True

The best I can explain: Copper has around twice the thermal conductivity of aluminum, around 400 W/M K for pure copper. Its main applications are in industrial facilities, power plants, solar thermal water systems, HVAC systems, gas water heaters, forced air heating and cooling systems, geothermal heating and cooling, and electronic systems.
