Answer : Option A
Explanation :
Metals are particularly good conductors of heat because their particles are very closely packed so the vibrations are passed on very quickly.
These drift slowly through the structure, giving metals their strength and other properties.
As the metal is heated, the free electrons closest to the heat source are heated.
