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.
