Which term best describes the practice of giving evidence under oath?

The term that best describes the practice of giving evidence under oath is testimony. Testimony refers specifically to a statement made by a witness, who is obliged to tell the truth about what they know regarding a case or legal matter, typically during a trial or deposition. This process is governed by legal standards that ensure the reliability and accountability of the information presented, as it is delivered under oath, emphasizing the legal obligation to provide truthful and accurate statements.

The other terms do not relate to the act of providing evidence under oath. A victim refers to an individual who has experienced harm, typically in the context of a crime but is not directly involved in the process of giving testimony in court. Intermittent is more commonly used to describe something that occurs at irregular intervals rather than to convey information in a legal context. Split sentence generally refers to a specific type of sentencing arrangement in the criminal justice system where a portion of the sentence is served in confinement followed by probation, and does not pertain to the act of providing testimony.
