Answer 2

B. All of the interviewers are policemen.

Step-by-step explanation:

Interviewer-induced bias happens when the interviewer is partial to the response they expect they will get and structure the way they interview to elicit that response, be it through phrasing of the questions or even the way they ask the question.

Given the position of a policeman and the topic involved, their preconceived notions about drug use and drug users can have an effect on the responses. Also their stand against drug use could manipulate the way they question the individual.

Not to mention, the respondents will also be on guard given that the study is on drug use, which is perceived as illegal. So the likelihood of an honest response is low.
