The non-metal present in steel is

Options

A. hydrogen
B. iodine
C. carbon
D. argon

Explanation

To determine the non-metal present in steel, we can follow these steps:

### Step-by-Step Solution:

1. **Understand what steel is**:
- Steel is an alloy, which means it is a mixture of different metals and sometimes non-metals.

2. **Identify the main components of steel**:
- The primary metal in steel is iron. Steel typically contains a significant amount of iron.

3. **Look for non-metal components**:
- In addition to iron, steel contains carbon, which is a non-metal. The carbon content in steel is usually less than 2%.

4. **Consider other elements in steel**:
- Steel may also contain small amounts of other elements like manganese, silicon, phosphorus, sulfur, and oxygen. However, among these, carbon is the most notable non-metal.

5. **Conclude the answer**:
- Since carbon is the only non-metal present in steel, we can conclude that the non-metal present in steel is carbon.

### Final Answer:
The non-metal present in steel is **carbon**.
