The best electrical conductor is

The correct option is C

silver

• Metals are the ones which are electropositive in nature and have the tendency to lose electrons and form cations. Due to these mobile electrons, metals exhibit high conductivity towards heat and electricity.
• Examples of metals: Aluminum (Al), Silver (Ag)
• Among the given elements, Silver (Ag) is the metal that exhibits maximum conductivity towards electricity.

Since Silver (Ag) is a comparatively better conductor of electricity than Gold (Au), Copper (Cu), and Aluminum (Al), options (A), (B), and (D) are incorrect.

Hence, option (C) is correct. Silver is the best electrical conductor.
