Which metal is highly resistant to corrosion?

Options

A. Fe
B. Cu
C. Ti
D. Al

Explanation

**Step-by-Step Solution:**

1. **Understanding Corrosion:**
- Corrosion is defined as the natural process that converts refined metals into more chemically stable forms, such as oxides. It involves the deterioration of materials due to chemical or electrochemical reactions with their environment.

2. **Identifying Corrosion-Resistant Metals:**
- Among various metals, some are known for their high resistance to corrosion. This resistance is crucial for applications where metals are exposed to harsh environments.

3. **Analyzing Aluminum:**
- Aluminum is one of the metals that exhibit excellent corrosion resistance. This is primarily due to the formation of a thin, protective oxide layer on its surface when exposed to air. This oxide layer prevents further oxidation and protects the metal underneath.

4. **Conclusion:**
- Based on the properties of metals and their behavior in corrosive environments, aluminum is identified as the metal that is highly resistant to corrosion.

**Final Answer:**
- The metal that is highly resistant to corrosion is **Aluminum**.
