The correct answer for this question is A.

Thus, Kathy Jenkins could elicit more truthful responses in comparison to in a personal interview. Furthermore, the mail questionnaire will avoid the problem of interviewer bias and will center the questionnaire to the research’s topic. Besides, a mail questionnaire allows participants to think better about their responses and is cheaper than a by personal or by phone questionnaire. But, Kathy should take into account that this type of questionnaires can have low response rate if the mail goes to or is seen  as junk mail.
