From the metals copper, iron, magnesium, sodium and zinc, select from metal which has a oxide that reacts with both acids and alkalies

Explanation

To solve the question, we need to identify which metal from the given list (copper, iron, magnesium, sodium, and zinc) has an oxide that reacts with both acids and alkalis. The oxides that can react with both acids and bases are known as amphoteric oxides.

### Step-by-Step Solution:

1. **Understand the Concept of Amphoteric Oxides**:
- Amphoteric oxides are those that can react with both acids and bases. This means they can neutralize acids to form salts and water, and they can also react with bases to form complex ions.

2. **Identify the Metals and Their Oxides**:
