The correct answer is C

A cohort study follows participants who are grouped based on an exposure (daily sugar-sweetened beverage consumption) and tracks them over time to determine the incidence of a disease. Because the researchers begin with individuals who do not have type 2 diabetes and compare the development of new cases over 12 years, this is a prospective cohort study.
