Which report may interview friends or co-workers about the applicant?

The Investigative Consumer Report is the correct response because it is specifically designed to gather detailed information about an individual's character, reputation, and lifestyle, which may include interviews with associates such as friends, neighbors, or co-workers. This kind of report is more comprehensive than a standard credit check, as it seeks qualitative insights into the applicant's behavior and interactions as perceived by others.

In contrast, a Fair Credit Report focuses primarily on the applicant's credit history and financial behavior, without delving into personal interviews or character assessments. A Consumer Affidavit is typically a self-reported document where applicants can provide information about themselves, but it does not involve third-party opinions. Lastly, an Employment Verification Report is concerned exclusively with confirming employment status and job history, without exploring personal characteristics or collecting testimonials from friends or colleagues.
