Solution

The correct option is A
Concentration of free electrons is higher in metals

The larger concentration of free electrons in metals as compared to non-metals makes them good conductors of heat. These free electrons, when heated begin to vibrate vigorously and collide with one another, thus transferring the heat energy.
