Answer:

b. The owner puts questionnaires in the changing rooms for students to fill out and drop into a secure box.

Explanation:

Option B is the one least likely to be biased. In this example, the owner wants to obtain information that is as objective as possible. Option A is not a good option because people who know the owner are most likely to want to please him with their answers. Option C is similarly biased because all of the students belong to the same class. Option D is not a good option because privacy is not maintained. The best option is option C.
