• A. Malleability
• B. Conductivity
• C. Density
• D. Ductility

Answer: (A)

Verified step by step guidance

1. Understand the meaning of each physical property listed: Malleability, Conductivity, Density, and Ductility.
2. Malleability is the ability of a material to be hammered or rolled into thin sheets without breaking.
3. Conductivity refers to the ability of a material to conduct electricity or heat, which is unrelated to shaping the material.
4. Density is the mass per unit volume of a substance and does not describe how a material can be shaped.
5. Ductility is the ability of a material to be drawn into wires, which is different from being pounded into sheets.
