Best quality of steel is manufactured by

Options

A. Siemen-Martin's open hearth process
B. Electrical process
C. Bessemer process
D. Blast furnace

Explanation

To determine the best quality of steel manufacturing process, we can analyze the given options step by step.

### Step 1: Understand the Options
The options provided are:
1. Martin's open-heart process
2. Electrical process
3. Basilar process
4. Blast furnace

### Step 2: Analyze Each Process
- **Martin's Open-Heart Process**: This is an older method of steel production that involves the use of an open hearth furnace. While it produces good quality steel, it is not the best compared to modern methods.

- **Electrical Process**: This method involves using an electric arc furnace (EAF). In this process, high current electric arcs are generated to melt steel scrap, converting it into liquid steel. This method allows for precise control over the composition of the steel and is known for producing high-quality steel.

- **Basilar Process**: This option is not commonly recognized in steel manufacturing and may refer to a less known or outdated method.

- **Blast Furnace**: This is a traditional method for producing pig iron, which can then be converted to steel. While effective, it does not produce the highest quality steel compared to the electric arc method.

### Step 3: Conclusion
After analyzing the options, the best quality of steel is manufactured by the **Electrical Process**. This method allows for better control over the steel's composition and results in higher quality steel.

### Final Answer
The best quality of steel is manufactured by the **Electrical Process**.
