Let's solve the problem step by step.

1. Understanding the problem: We need to find out how many moles of copper (Cu) are present in four moles of copper (II) sulfate (CuSO₄).

2. Chemical composition analysis: Each mole of copper (II) sulfate (CuSO₄) contains one mole of copper (Cu). This is because the chemical formula CuSO₄ indicates that there is one copper atom in each formula unit.

3. Calculating moles of copper:
- Given: 4 moles of CuSO₄.
- Since each mole of CuSO₄ contains 1 mole of Cu, the number of moles of Cu in each mole of CuSO₄ is 1.

4. Multiplying the moles:
- Number of moles of Cu = (Number of moles of CuSO₄) × (Moles of Cu per mole of CuSO₄)
- Number of moles of Cu = 4 × 1
- Number of moles of Cu = 4

Therefore, there are 4 moles of copper (Cu) in four moles of copper (II) sulfate (CuSO₄).
The correct answer is:
```
