Professor Scott Conducts Research on Teenage Risk-Taking Behavior

Professor Scott conducts research on teenage risk-taking behavior. He would like to develop a hypothesis on the parental influence on teenage risk-taking at the extreme end of the spectrum, with a focus on teenagers who sail around the world alone. Would a case study be an appropriate first step, and why or why not?

A) Yes, because Professor Scott already knows that parents are the driving influence behind teenage circumnavigation.
B) No, because it will not generate a sufficient amount of data to be tested statistically.
C) Yes, because teenage circumnavigators are rare and the data will help generate new, or possibly falsify existing, hypotheses.
D) No, because case studies are too idiosyncratic and lack scientific rigor.
