Question 43

After a race between five horses, five friends meet and discuss the results. Each bet on a different horse. The people who bet on the first- and last-placed horses both lie; the other three tell the truth. They say:
Alex: “Igor's horse finished at least two places ahead of Enrica's.”
Enrica: “My horse won.”
Igor: “Osvaldo's horse finished ahead of mine.”
Osvaldo: “My horse did not finish in the first three.”
Umberto: “My horse did not win, but finished immediately after Alex's and immediately before Enrica's.”
Who bet on the horse that finished third?
(A) Alex (B) Igor (C) Osvaldo (D) Umberto
