The best conductor of electricity amongst the following is

Aluminium
Copper
Silver
Gold

The correct answer is (c) Silver. Silver is the best conductor of electricity, followed by copper, gold, and aluminum. Silver is a very soft metal, so it is not often used in electrical wiring. Copper is a good conductor of electricity and is also strong and durable, so it is often used in electrical wiring. Gold is a very expensive metal, so it is not often used in electrical wiring. Aluminum is a good conductor of electricity and is also lightweight, so it is often used in electrical wiring.

Here is a table showing the electrical conductivity of different metals:

Metal | Electrical Conductivity (Siemens per meter)
——- | ——–
Silver | 62.5
Copper | 59.6
Gold | 45.3
Aluminum | 36.8

As you can see, silver is the best conductor of electricity, followed by copper, gold, and aluminum.
