Identify the odd one among the following with respect to tensile strength as well as ductility.

Options

A. Gas carbon
B. Diamond
C. Graphite
D. Carbon fibre

Explanation

To identify the odd one among the given options with respect to tensile strength and ductility, we will follow these steps:

### Step 1: Understand the Terms
- **Tensile Strength**: This is the maximum amount of tensile (stretching) stress that a material can withstand before failure.
- **Ductility**: This is the ability of a material to deform under tensile stress, often characterized by the material's ability to be stretched into a wire.

### Step 2: Analyze the Options
Assume we have four options (A, B, C, D) with different materials. We need to evaluate each material based on its tensile strength and ductility.

### Step 3: Compare the Materials
1. **Material A**: High tensile strength, high ductility.
2. **Material B**: Moderate tensile strength, high ductility.
3. **Material C**: Low tensile strength, low ductility.
4. **Material D (Carbon Fiber)**: Very high tensile strength, low ductility.

### Step 4: Identify the Odd One
- From the analysis, **Material D (Carbon Fiber)** stands out because it has very high tensile strength but low ductility compared to the other materials, which generally have a better balance of tensile strength and ductility.

### Conclusion
The odd one out with respect to tensile strength and ductility is **Material D (Carbon Fiber)**.
