The correct answer is B. The CFE Manual states that authenticity is supported by establishing a chain of custody, which is both a process and a document showing who had possession of an item and what was done with it. The chain of custody is important because it helps prove that the evidence has not been materially altered or changed from the time it was collected until it is produced in court. That is exactly the concern raised in this question.
The Manual further explains that establishing chain of custody generally involves documenting each person who had control of the evidence, when and how it was received, how it was stored, whether any changes occurred while it was in that person's possession, and how it left that person's custody. It is therefore the primary method for preserving and proving authenticity.
The other options do not address authenticity as directly. Limiting release only to a judge is not the standard legal requirement. Requiring court orders from opposing parties may relate to access disputes, not authenticity. Preventing all others from ever handling the evidence is also unrealistic and unnecessary if possession is properly documented. For CFE purposes, the best practice is to maintain a clear, documented chain of custody, so B is the correct answer.

The Fraud Examiners Manual notes that predictive modeling and data analysis allow fraud examiners to detect fraud by using historical data to forecast future trends and anomalies. This matches option B.

Predictive analytics is defined as:
"the use of historical data combined with statistical, analytical, and machine learning techniques to create models that capture trends and produce forecasts".
So, option C best describes predictive analytics.

CFE guidance on tracing illicit transactions explains that financial institution records-especially account statements-are among the most important sources for tracing because they can reveal transfers, counterparties, and leads to additional evidence. In the cryptocurrency context, the Manual specifically notes that when reviewing account statements, fraud examiners should look for transactions involving cryptocurrency exchanges and for payments to or deposits from such exchanges. Those banking "on-ramps
/off-ramps" can connect a real-world identity (account holder) to crypto activity and help establish ownership or control indicators (e.g., exchange deposits/withdrawals, recurring transfers, related payment records).
Option B is incorrect because public blockchains show transactions and addresses, but they generally do not contain direct personal identifiers. Option C is too broad and not supported as a "most accurate" statement across jurisdictions; requirements vary and many exchanges apply identification controls. Option D is incorrect because the Manual states that most cryptocurrencies rely on public blockchains that make transactions visible, not private blockchains. Therefore, A is the most accurate statement: ownership clues can sometimes be derived from bank statements that show exchange-related activity and related financial footprints.

In civil law criminal proceedings, judges usually play a more active role than they do in common law adversarial systems, and a judge often serves as the primary fact finder. However, it is inaccurate to say that judges serve as the fact finder in every criminal case in every civil law jurisdiction. Some civil law jurisdictions use mixed panels made up of professional judges and laypersons, or other forms of lay participation, especially in more serious matters. Option B reverses the general pattern by stating that juries typically serve as fact finders. Options C and D are too absolute because fact-finding structures vary by jurisdiction. Therefore, option A is the most accurate statement.
