What is the most abundant metal on Earth?

Aluminum
Iron
Iron
Copper

The correct answer is: Aluminum

Aluminum is the correct answer because it comprises approximately 8% of the Earth's crust, making it the most abundant metal. Iron, while present in large quantities, makes up only about 5% of the Earth's crust. Copper, while also abundant, is not as prevalent as aluminum. Therefore, A is the most accurate and abundant metal on Earth.
