Which of the following defines 'inadmissible' evidence?

The term 'inadmissible' evidence refers specifically to evidence that cannot be utilized in a court of law. This can stem from various reasons, such as the evidence being obtained in violation of constitutional rights, failing to meet the legal standards for relevance or reliability, or not adhering to procedural rules.

Inadmissible evidence is distinct from other types of evidence, as it does not contribute positively to establishing the facts of a case or supporting a legal argument. Its exclusion is typically aimed at maintaining the integrity of the judicial process and protecting individuals' rights. Thus, the definition captured in the correct answer aligns perfectly with this legal understanding, emphasizing that such evidence has no place in court proceedings and cannot be considered by a judge or jury when making determinations regarding a case.
