The correct answer to this question is C. If C is the number of new asthma cases in Oklahoma and B is the population of the residents of Oklahoma, then you could divide C by B and then multiply that by the incidence rate of asthma (100,000).

You would not want to use the number of residents of Oklahoma who have been previously diagnosed, because you are trying to get an incidence rate of asthma. You want to use the value that is the population at a certain time when you know how many people developed asthma at that time.
