Explanation:
Of the options provided the best reason for choosing interviews as your research methodology is that the study is aimed at gleaning detailed information on a subject and there needs to be an effort to dive deep into the data. The disadvantage of this method is that it tends to be time-consuming and the analysis needs to be done more manually than the results of a survey.
