Sensitivity = (true positives) / (true positives + false negatives)
In this case, true positives = 72 (those who have sickle cell disease and tested positive for it)
False negatives = Total number of patients with sickle cell disease - true positives = 80 - 72 = 8
Therefore, sensitivity = 72 / (72 + 8) = 0.9 or 90%.
So, the best choice is C) 90%.
