What awareness do the police have about the story he told?

The correct answer indicates that the police have recognized that the story told by the individual is untrue. This understanding reflects a clear comprehension of the situation, suggesting that the police have critically assessed the details of the story and found inconsistencies or falsehoods within it. This awareness implies a level of investigation and analysis, allowing law enforcement to take appropriate action based on the realization that the information provided is not factual.

Contextually, being aware that the story is untrue points to the police's ability to discern truth from falsehood during their inquiries. Other options present variations of suspicion or doubt regarding the individual's credibility, which do not align with the definitive conclusion that the police clearly understand the story is false. Thus, the acknowledgment of the untruth directly impacts the police's approach in the investigation and any subsequent actions they may take.
