Which problem is reduced by separation of powers in a Constitution?

Correct answer: The danger of one institution misusing power

The correct answer is C: separation of powers reduces the danger that one institution will misuse power. A Constitution distributes government functions among institutions such as the legislature, executive and judiciary. Each institution has its own area of responsibility, and each may check the actions of the others. This prevents all authority from being concentrated in one person or body. Option A is not the direct purpose of separation of powers; citizen participation is more closely related to democracy and elections. Option B is an important possible result of constitutional arrangements, but it is not the problem named in the question; independence of the judiciary is an institutional safeguard. Option D is also a benefit of constitutional government, not the direct danger being reduced here. Remember: separation of powers means dividing authority to prevent concentration and misuse.
