Final Answer : B, Explanation :  The appropriate sequence of steps to determine the prevalence, incidence, and risk factors for a disorder is to first identify the population of interest, then identify a random sample from that population, interview participants to collect data on their disorder status and risk factors, and finally estimate the prevalence and incidence of the disorder within each category of risk factors. Option B correctly follows this sequence, while the other options have either skipped a step or placed them in the wrong order.
