The correct options are
A It has to maintain many institutions at different centres of power
B Each state has its own organs and departments
The federal system of government is more expensive since it has to maintain many institutions at different centres of power. Each state has its organs and departments, with many officials appointed by the government. The state governments sometimes create hindrance in the foreign policy, and with every state government having the power to pass its laws and policies, there is often a lack of uniformity in the administration.
