Verified by Experts

The correct Answer is:

Metals show a similar range of thermal conductivities, silver being the highest and copper the second highest. It it because of its high thermal conductivity that copper is the preferred metal for cooking pots. The thermal conductivity of manganese is only `2%` of that of silver.
