<h2>
Answer:Option F</h2>
Explanation:
Metals have few number of electrons in their valence shell.
The force with which the nucleus of the metal atom is pulling the electron towards itself is lower on the valence shell because the distance between the nucleus an valence shell is large.
So,there are a lot of free electrons in metals.
When the ends of metals are at different potential,electrons flow from one end to another to balance the potential.This feature of metals allows them to conduct electricity.
Similarly,when the ends of metals are at different temperatures,conduction will take place and electrons are the carriers of conduction.This feature of metals allows them to conduct heat.
So,metals are good conductors of heat and electricity.
