In which case was the concept of "fruit of the poisonous tree" addressed?

The concept of "fruit of the poisonous tree" originates from the case of Wong Sun v. United States, but among the options provided, Bram v. U.S. is the most relevant in discussing the implications of unlawful police action.

In Bram v. U.S., the court determined that evidence obtained through coercive or improper means is inadmissible in court, reinforcing the principle that if the initial evidence (the "tree") was obtained unlawfully, then any further evidence derived from it (the "fruit") is also tainted and inadmissible. This ruling underscores the importance of lawful procedures in law enforcement and serves as a foundation for protecting individuals' rights against unlawful search and seizure.

The other cases listed do not directly address this specific principle; although they may involve important legal issues concerning police practices and Fourth Amendment rights, they do not specifically focus on the exclusion of evidence obtained through improper means in the same way Bram does.
