As we have learned

Thermal conductivity of metals -

On heating a part of the metal, the kinetic energy of the electron in that region increase. The energised electron moves rapidly to the cooler part and gives their excess kinetic energy to other electrons in the cooler part of the metal.Thus heat is conducted through metal.

-

 

For good conductors, there must be free electrons present in the metal.

Therefore, Option(2) is correct.
