A2. As part of the investigation, four suspects were arrested. Each gave one statement. Žan: "Among the suspects, I am the only innocent one."

Alen: "Among the suspects, I am the only guilty one."

Zala: "All suspects are innocent."

Beno: "At least two of the suspects are guilty."

Further investigation revealed that at least one of the suspects was guilty and that the innocent ones told the truth, while the guilty ones lied. How many suspects were guilty?
(A) 1
(B) 2
(C) 3
(D) 4
(E) It is impossible to determine.
A2. Alen could not have been innocent, for then he would have been telling the truth, but then he would have to be guilty according to his words. Alen is therefore guilty. This means that Zala was lying, so she is also guilty. It follows that Beno was telling the truth, so he is innocent. This means that Žan was lying, so he is also guilty. Therefore, exactly three suspects are guilty, these are Žan, Alen, and Zala.
