To evaluate this plan, a survey of public transportation passengers was planned to answer these three questions. What proportion of passengers rides the bus every day? What proportion of passengers is interested in the new route? How do these proportions change for different regions of the city? What are the cases and variables in this survey? The cases are all people living in the city. One variable is whether the individual uses the bus every day. The second variable records which passengers expressed interest in the proposed new route. The third variable keeps track of which regions of the city survey respondents live in. A The cases are the people who respond to the survey.

The survey here is of all the people who use public transportation (not all the people in the city). So the survey here is specific, as in who will be asked to answer the 3 questions. So the cases here are the people who respond to the survey, and hence Option B is the correct answer.
