All four ladies, finalists of a trivia show, agreed among them, prior to facing the MC, to include only one true fact in their statements.
Since each contestant represented a different country, the ladies were requested to address the origin of their fellows.
Those were their answers:
Alla: Bella is from France and Carla from Canada.
Bella: Della is from Spain and Bella from Canada.
Carla: Alla is from Canada and Carla from France
Della - was not interviewed and therefore said nothing.

Is it possible to determine for each lady, what country she represented?
