Answer

To determine which of the given materials has the maximum iron content, we will analyze the iron percentage in each option provided.

### Step-by-Step Solution:

1. **Identify the Materials**: The materials we need to compare are:
- Cast Iron
- Wrought Iron
- Pig Iron
- Stainless Steel

2. **Determine Iron Content**: We need to know the percentage of iron in each of these materials:
- **Cast Iron**: Contains approximately 92% iron.
- **Wrought Iron**: Contains approximately 99.4% iron.
- **Pig Iron**: Contains approximately 92% iron.
- **Stainless Steel**: Contains approximately 50% iron.

3. **Compare Iron Content**: Now, we will compare the percentages of iron:
- Cast Iron: 92%
- Wrought Iron: 99.4%
- Pig Iron: 92%
- Stainless Steel: 50%

4. **Identify the Maximum**: From the percentages listed, we can see that:
- Wrought Iron has the highest iron content at 99.4%.

5. **Conclusion**: Therefore, the material with the maximum iron content is **Wrought Iron**.

### Final Answer:
Wrought Iron has the maximum iron content.
