Solution

The correct option is A Metallic
The thermal conductivity of silver and copper is high because they have metallic bonding.

Silver and copper are metals. They form metallic bonds. They contain mobile electrons immersed in a sea of positively charged metal cations.

These mobile electrons can move from one end of metal to other end. Hence, they conduct electricity.

Therefore, option A is correct.
