The two metals involved in the galvanization process are

Options

A. iron and copper
B. iron and zinc
C. zinc and copper
D. copper and aluminium

Explanation

**Step-by-Step Solution:**

1. **Understand the Concept of Galvanization:**
- Galvanization is a process used to protect iron from corrosion. It involves coating the iron with another metal to prevent rusting.

2. **Identify the Metals Used:**
- In the galvanization process, iron is the base metal that needs protection. The metal used for coating is zinc.

3. **Explain the Role of Each Metal:**
- Iron is susceptible to rusting when exposed to moisture and air. When iron rusts, it forms iron oxide, which deteriorates the metal.
- Zinc, when applied as a coating, acts as a protective barrier. It does not corrode as quickly as iron, thus preserving the integrity of the iron beneath it.

4. **Review the Options Provided:**
- Option A: Iron and Copper - Incorrect, as copper is not used in galvanization.
- Option B: Iron and Zinc - Correct, as this is the process of coating iron with zinc.
- Option C: Zinc and Copper - Incorrect, as copper is not involved.
- Option D: Copper and Aluminum - Incorrect, as neither is used in galvanization.

5. **Conclusion:**
- The two metals involved in the galvanization process are iron and zinc.

**Final Answer:**
The two metals involved in the galvanization process are **iron and zinc**.
