The phrase 'the matter speaks for itself' implies which of the following?

• A. A medical expert must testify.
• B. No witness is necessary.
• C. The trial will rely on records.
• D. The patient's testimony is decisive.

Answer: (B)

When a matter speaks for itself, the facts are so clear from the evidence already in hand that no witness is needed to establish them. In a dental-legal context, that often means the record or chart alone proves the point, without calling anyone to testify. So the best fit is that no witness is necessary. The other ideas don’t fit because requiring an expert testifies suggests the facts aren’t self-evident, and while records can be central, the phrase focuses on the necessity of testimony rather than how the trial will be conducted; saying the patient’s testimony is decisive would imply a witness is needed, which contradicts the expression.
