Detailed Solution

Concept: The conductivity of a metal is determined by the ease with which electrons can travel through it. The electrons in a metal will migrate and allow electricity to flow if a potential difference is introduced to it at particular spots. High electron mobility materials are good conductors, while low or negligible electron mobility materials are referred to as insulators.
Copper, silver, aluminium, gold, steel, and brass are all common electrical conductors. Each has its own set of characteristics that make it suited for various applications. The most common conductors are copper and silver.
The resistivity of a metal is a physical property that aids in the selection of the best conductor. Resistivity is defined as a measurement of a material's resistance to the flow of an electric current. Conductors who are good at what they do
Good conductors do not resist the flow of current. Therefore, the lesser the resistivity of a metal, the better conductor it is.
Hence, option 3 is correct.
