Evidence must be relevant to be admissible. Relevance means the evidence has a tendency to make a fact of consequence more or less probable than it would be without the evidence. If the judge refuses to admit the evidence because it does not affect the likelihood of any disputed fact, the judge is finding that it lacks relevance. Option A is incorrect because reliability concerns trustworthiness, not whether the evidence affects a material fact. Option B refers to authentication, which asks whether the item is what it purports to be. Option C refers to legal protections that prevent disclosure, such as attorney-client privilege. The wording in the question directly tracks the relevance standard, making option D correct.
