General metallurgy: Identify the most malleable metal among common metals. Malleability refers to the ability of a metal to be hammered into thin sheets without breaking. Choose the correct metal.

Concept

• Malleability = ability to be hammered/rolled into sheets.
• Gold > Silver > Aluminium ≈ Copper ≫ Iron for malleability.

ReasoningGold can be beaten into extremely thin leaf (∼0.1 µm), making it the most malleable common metal.

Final AnswerGold.
