### Step-by-Step Solution:

1. **Understanding the Parliamentary System**:

2. **Identifying the Key Roles**:

3. **Analyzing the Options**:
- **President**: While the President is the ceremonial head of state and represents the unity of the nation, the real powers are not vested in the President in a parliamentary system.

- **Judiciary**: The Judiciary interprets laws and ensures justice, but it does not hold executive powers.
- **Council of Ministers headed by the Prime Minister**: This is the executive branch that actually runs the government and makes policy decisions.

4. **Conclusion**:
