What does extrinsic impeachment method imply?

The extrinsic impeachment method revolves around introducing new evidence or witnesses that challenge the credibility of a witness's testimony. This method allows a party to bring in outside information that indicates a potential bias, motive to lie, or other factors that may affect the witness's reliability.

In extrinsic impeachment, the goal is to provide independent evidence to undermine a witness's credibility rather than relying solely on prior statements made by the witness themselves or focusing merely on their present testimony. This approach can include corroborating or contradicting evidence that was not previously part of the case, such as bringing in new witnesses who can testify regarding the witness's character or prior behavior that implies a lack of credibility.

The other methods mentioned in the options refer to different approaches to impeachment, but they do not encapsulate the essence of what extrinsic impeachment entails, which emphasizes the introduction of external evidence or witnesses.
