The process where tin is used to preserve edible food materials is called……………..

Options

A. galvanization
B. tinning
C. alloying
D. electroplating

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about a specific process that involves using tin to preserve food. We need to identify the term that describes this process.

2. **Identifying the Process**: The process of using tin for preservation involves coating food materials with thin sheets of tin. This helps protect the food from spoiling and maintains its taste.

3. **Defining the Term**: The term for this process is known as "tinning." Tinning refers to the application of a thin layer of tin to food items to prevent them from becoming rancid.

4. **Differentiating from Other Processes**: It is important to differentiate "tinning" from other similar processes:
- **Galvanization**: This is the process of coating iron or steel with zinc to prevent rusting.
- **Alloying**: This involves mixing different metals to enhance their properties.
- **Electroplating**: This is a method of depositing a layer of one metal onto another metal.

5. **Conclusion**: Based on the above understanding, the correct answer to the question is "tinning."

**Final Answer**: The process where tin is used to preserve edible food materials is called **tinning**.
