In the context of game theory, which of the following scenarios represents a Pareto efficient outcome?

A Pareto efficient outcome in game theory occurs when no player can be made better off without making another player worse off. This means that resources are allocated in such a way that any change would benefit one player at the expense of another. For example, imagine two friends sharing a pizza. If one friend takes more slices, the other gets fewer, which makes it impossible for both to be happier without changing the distribution. Therefore, a scenario where both friends have an equal number of slices and are satisfied with their share would be considered Pareto efficient, as any attempt to change that would leave one of them unhappy.
