B. The exclusionary rule, derived from the Fourth Amendment, prevents the evidence from being used against the suspect.
The Fourth Amendment to the U.S. Constitution protects against unreasonable searches and seizures by the government. The exclusionary rule is a legal principle that generally prevents the use of evidence obtained in violation of the Fourth Amendment from being admitted in a criminal trial.
Since the question states that the evidence was obtained through a warrantless search of the woman’s home by the police, it would likely be considered an unreasonable search and seizure under the Fourth Amendment. Therefore, the exclusionary rule would apply, and the evidence obtained from the illegal search would be inadmissible in a criminal trial against the defendant.
The other options are incorrect because the due process rights of the Fifth Amendment (option A) are not directly relevant to the admissibility of evidence obtained through an illegal search, the mere existence of evidence suggesting illegal activity does not override the exclusionary rule (option C), and the exclusionary rule applies to both state and federal courts (option D).
