The correct answer is C. The CFE Manual explains that in adversarial systems, one of the most common methods of impeachment is to show that the witness made prior inconsistent statements. Impeachment is used to attack a witness's credibility, reliability, or truthfulness. If a witness previously said something materially different from what the witness now says at trial, opposing counsel can use that inconsistency to suggest that the testimony is unreliable or false.
The other options do not describe impeachment. Option A, testifying from personal knowledge, generally supports credibility rather than undermines it. Option B, having a reputation for truthfulness, also strengthens credibility and is the opposite of impeachment. Option D, possessing a strong ability to observe, similarly suggests reliability rather than weakness. The Manual lists several common impeachment methods, including showing bias, impaired ability to observe, felony convictions, a reputation for untruthfulness, and prior inconsistent statements. Among the choices provided, only C matches one of those recognized impeachment techniques. Therefore, in an adversarial process, an attorney may impeach an opposing witness by proving that the witness previously made inconsistent statements, making C the correct answer.

The correct answer is B. The CFE Manual explains that in adversarial proceedings, expert witnesses are usually chosen by the parties to the litigation, although the court may also appoint an independent expert in some circumstances. By contrast, in inquisitorial jurisdictions, judges typically appoint their own experts to evaluate technical matters. That makes option B the most accurate statement.
Option A is incorrect because it reverses the usual adversarial rule. Courts in adversarial systems may appoint experts, but they are not generally the only ones allowed to do so. Option C is incorrect because juries do not generally select expert witnesses in inquisitorial jurisdictions; the judge typically performs that function.
Option D is also inaccurate because the parties are not primarily responsible for selecting experts in inquisitorial systems; again, that role usually belongs to the court or judge. The Manual further notes that in inquisitorial systems, expert selection is often viewed as an extension of the court's authority and discretion.
Therefore, the best statement is that parties usually choose experts in adversarial cases, while the court may also appoint experts when appropriate.
