Which of the following has highest tensile strength ?

Options

A. Diamond
B. Copper
C. Graphite
D. Sulphur

Explanation

To determine which of the given materials has the highest tensile strength, we need to analyze the properties of each option provided. Let's break it down step by step.

### Step-by-Step Solution:

1. **Understanding Tensile Strength**:
- Tensile strength is defined as the resistance of a material to breaking under tension. It indicates how much load a material can withstand without failing.

2. **Identifying the Options**:
- The options provided are: Diamond, Copper, Graphite, and Sulphur.

3. **Analyzing Each Material**:
- **Diamond**:
- Diamond is a form of carbon and is known for its hardness. However, while it has high compressive strength, its tensile strength is not as high as metals.
- **Copper**:
- Copper is a metal and is known for its good tensile strength. It is commonly used in electrical wiring due to its ability to withstand stress.
- **Graphite**:
- Graphite is another form of carbon and is used in pencils. It has good conductivity but is brittle and does not have high tensile strength.
- **Sulphur**:
- Sulphur is a non-metal and has low tensile strength. It is brittle and breaks easily under tension.

4. **Comparing the Tensile Strengths**:
- Among the materials analyzed, Copper stands out as a metal with good tensile strength.
- Although Diamond is hard, it does not have the same tensile strength as metals like Copper.

5. **Conclusion**:
- Based on the analysis, Copper has the highest tensile strength among the options provided.

### Final Answer:
**Copper** has the highest tensile strength among the given options.
