From among the set of metals-sodium, zinc, iron, copper and silver, select the following giving equation for reaction.
One metal which will displace copper from copper sulphate solution.

Explanation

To solve the question of which metal will displace copper from copper sulfate solution, we can follow these steps:

### Step 1: Understand the Reactivity Series
The reactivity series is a list of metals arranged in order of decreasing reactivity. Metals higher in the series can displace metals lower in the series from their compounds.

### Step 2: Identify the Metals
The metals provided are:
- Sodium (Na)
