Aluminium foil can be made from aluminium by using

Options

A. its thermal and electrical conductivity.
B. its malleable property.
C. its sonorous property.
D. All the above

Answer

To determine how aluminum foil is made from aluminum, we need to identify the property of aluminum that allows it to be transformed into a thin sheet. Let's go through the options provided step by step:

1. **Understanding the Question**: The question asks which property of aluminum is utilized to make aluminum foil.

2. **Analyzing the Options**:
- **Option A: Thermal and Electrical Conductivity**: While aluminum is known for its excellent thermal and electrical conductivity, these properties are not relevant to the process of making aluminum foil. Therefore, this option is not correct.

- **Option B: Malleable Property**: Malleability is the ability of a metal to be hammered or pressed into thin sheets without breaking. This property is essential for creating aluminum foil, as it allows aluminum to be flattened into a thin layer. This option is likely correct.

- **Option C: Sonorous Property**: The sonorous property refers to the ability of a metal to produce sound when struck. While aluminum does have this property, it does not play a role in the process of making aluminum foil. Thus, this option is also incorrect.

- **Option D: All of the Above**: Since options A and C are incorrect, this option cannot be correct either.

3. **Conclusion**: The only property that is relevant to the making of aluminum foil is the malleable property. Therefore, the correct answer is **Option B: Malleable Property**.

### Final Answer:
Aluminum foil can be made from aluminum by using its **malleable property**.
