Which of the following metal is highly elastic?

Options

A. Copper
B. Silver
C. Aluminium
D. Gold

Explanation

To determine which of the following metals is highly elastic, we will analyze the properties of the metals mentioned in the question.

### Step-by-Step Solution:

1. **Understanding Elasticity**:
- Elasticity refers to the ability of a material to return to its original shape after being deformed. In metals, this means they should resist deformation when force is applied.

2. **Identifying the Metals**:
- The question likely presents a list of metals (not specified here). Common metals to consider include copper, silver, aluminum, and gold.

3. **Analyzing Each Metal**:
- **Copper**: Known for its ductility, which means it can be drawn into wires, but it is not the most elastic metal.
- **Silver**: While it has good malleability and ductility, it is not the most elastic compared to other metals.
- **Aluminum**: This metal is known for its light weight and malleability, but it can bend easily, indicating less elasticity.
- **Gold**: Gold is highly malleable and can be shaped into thin sheets, suggesting it is also less elastic.

4. **Comparing Elasticity**:
- Among the metals listed, we need to find the one that resists deformation the most. Typically, metals like steel or tungsten are known for their high elasticity, but from the common metals mentioned, silver is often recognized for its balance of properties, though it is not the most elastic.

5. **Conclusion**:
- Based on the analysis, if we were to choose from the common metals, silver could be considered the most elastic among the options provided, but it’s important to note that metals like steel are generally more elastic than the ones listed.

### Final Answer:
Silver is the most elastic metal among the common options provided.
