To determine which party won the elections, we need to analyze each statement given by A, B, and C and identify which person is wrong, as only one is incorrect.
Let's evaluate their statements one by one:
- A said: "Either Freedom Party or Green Party won the elections." This implies if A is correct, Freedom Party or Green Party must have won.
- B said: "Freedom Party won." This statement directly asserts that Freedom Party won the elections.
- C said: "Neither Freedom Party nor Green Party won the elections." This contradicts A's statement entirely, as C is saying neither party won.
Now, let's consider the cases where each person might be wrong and analyze the outcomes:
- If A is wrong, then neither Freedom Party nor Green Party won, which means C is correct. Hence, B must also be wrong because B and C’s statements are mutually exclusive.
- If B is wrong, then Freedom Party did not win. This implies C is correct, and therefore, A must also be wrong since Green Party did not win either (according to C).
- If C is wrong, then either Freedom Party or Green Party won. A said one of these parties won. B said Freedom Party specifically won. So, if C is wrong, Freedom Party must have won to satisfy both A and B.
Hence, the only scenario where only one person is wrong is when C is wrong, meaning Freedom Party won the elections.
