The purpose of constructing a ROC curve in diagnostic tests is to compare the accuracy of different diagnostic tests. Additionally, it can also be used to establish the best cutoff point for the test, determine the sensitivity and specificity of the test, and calculate the area under the curve (AUC). Therefore, the correct alternative is b) II and III are correct.
