The Fraud Examiners Manual specifies that admission-seeking interviews should only be conducted when:
"There is a reasonable probability that the respondent has committed the act in question.
All other reasonable investigative steps have been completed.
The interviewer can reasonably control the place, time, and subject matter of the interview." There is no requirement that the examiner must be sure no one else was involved. Therefore, C is correct.

The recommended questioning order is:
"As a general rule, questioning should proceed from the general to the specific; that is, it is best to seek general information before seeking details".
This ensures the respondent provides a free narrative before narrowing down to specifics.

"Once a suspect utters a denial, it becomes extremely difficult... therefore, the interviewer must prevent an outright denial. Fraud examiners can use several techniques to stop or interrupt denials, including delays, repeated interruptions, and reasoning".
Thus, the correct answer is D.

The Manual defines leading questions as those that contain or suggest the answer:
"Leading questions... are framed in a way that evokes a specific reply... most commonly used to confirm facts already known... Example: 'You got promoted, right?'" Nathaniel's question, "When were you promoted to manager?" presumes the promotion occurred. This leads the subject by suggesting a fact that may not be true. It is not open (does not invite free narration), not complex (it asks one thing), and not closed (doesn't call for yes/no but presumes an answer).

Pretexting is defined as impersonating someone else or making false/misleading statements to obtain information. Many jurisdictions specifically prohibit pretexting against financial institutions, which includes pretending to be a customer to access their bank account information.
