Preferred Method of Conducting Interviews for Human Trafficking Compliance Review

Explanation:

The preferred method of conducting interviews during a human trafficking compliance review is B. In-person interviews. In-person interviews are generally more effective for sensitive topics such as human trafficking because they allow for the observation of non-verbal cues, ensure better privacy, and facilitate a deeper level of trust between the interviewer and the interviewee. Although other methods like telephone interviews, email correspondence, and written surveys can be used, they may not be as effective in capturing the complexity and nuances of information related to compliance matters in human trafficking. It is essential during interviews to not only ask the right questions but also to understand the context of the responses given, something that is often better achieved in person.
