Answer 1

C. Face-to-face interviews.

Face-to-face interviews are most likely to make a guarantee of anonymity difficult because the interviewer and the participant are present in the same physical space, making it easier to associate responses with the individual. Other methods, like mailed questionnaires or unobtrusive measures, are more likely to preserve anonymity since the identity of the respondent can be kept confidential.
