Steel consists of.....percentage of carbon-

Options

A. `3.1 -4.5%`
B. `2.2 -3.1%`
C. `0.15 -0.28%`
D. `0.15 -1.5%`

Answer

To determine the percentage of carbon in steel, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Steel Composition**:
- Steel is an alloy primarily made of iron and carbon.

2. **Identifying the Percentage of Iron**:
- In steel, iron constitutes approximately 98-99% of the total composition.

3. **Determining the Carbon Content**:
- The percentage of carbon in steel is relatively low compared to iron. The typical range for carbon content in steel is from 0.15% to 1.5%.

4. **Evaluating the Options**:
- If options are provided, we need to check which one aligns with the known range of carbon content in steel.
- For example, if an option states 0.15% to 0.28%, it does not cover the full range and is therefore incorrect.

5. **Conclusion**:
- Based on the information, the correct answer regarding the percentage of carbon in steel is that it ranges from 0.15% to 1.5%.

### Final Answer:
Steel consists of approximately **0.15% to 1.5%** of carbon.
