Options

A. Steel, Rubber, Copper, Glass
B. Rubber, Copper, Glass, Steel
C. Rubber, Glass, Steel, Copper
D. Rubber, Glass, Copper, Steel

Explanation

To determine the order of increasing coefficient of elasticity for Copper, Steel, Glass, and Rubber, we need to understand the concept of elasticity and how it relates to these materials.

### Step-by-Step Solution:

1. **Understand Coefficient of Elasticity**: The coefficient of elasticity (also known as Young's modulus) measures a material's ability to deform elastically (i.e., non-permanently) when a force is applied. A higher coefficient indicates that the material is stiffer and less prone to deformation.

2. **Identify the Materials**: The materials we are comparing are Copper, Steel, Glass, and Rubber.

3. **Research the Coefficients**:
- **Rubber** has a low coefficient of elasticity because it is very flexible and can stretch significantly.
- **Copper** has a moderate coefficient of elasticity, being more rigid than rubber but less so than steel.
- **Glass** has a higher coefficient of elasticity than copper, as it is more rigid and does not deform easily.
- **Steel** has the highest coefficient of elasticity among these materials, making it very stiff and resistant to deformation.

4. **Order the Materials**: Based on the coefficients of elasticity:
- Rubber (lowest)
- Copper
- Glass
- Steel (highest)

5. **Final Arrangement**: Therefore, the order of increasing coefficient of elasticity is:
- Rubber < Copper < Glass < Steel

### Conclusion:
The increasing order of the coefficient of elasticity for the materials is:
**Rubber < Copper < Glass < Steel**
