Quizplus · Accepted Answer

The Arrow impossibility theorem, also known as Arrow's paradox, shows that there is no perfect or flawless voting system that can fully reflect the preferences of all individuals in society. It proves that there will always be trade-offs and compromises in any system of democratic decision-making. Therefore, the best choice is C, which states that all voting systems are flawed as mechanisms for social choice.
