Choose the correct statements about the ROC curve.
A. By plotting the true-positive rate against the false-positive rate for different threshold values, the ROC curve can be used to select the optimal model.
B. ROC stands for Receiver Operating Characteristic curve, which was originally developed to detect enemy aircrafts on radar.
C. The ROC curve is a useful diagnostic tool for determining the optimal classification model.
D. The ROC curve was originally developed to optimize healthcare and detect congestive heart failure readmission rate.

Answer:

B

Explanation:

The ROC stands for Reviever Operating Characteristics curve ehic was originally developed to detect enemy aircrafts on reader

The correct statement about the ROC curve is that  ROC stands for the Receiver Operating Characteristic curve, which was originally developed to detect enemy aircraft on radar. Thus, option B is correct.

A curve can be defined as the relation that can be between the teo element. this is represented by the graph that is formed on the basis of the change in the elements that are surrounding it. If there is a change in one thing then there can also be a change in another and it may have an effect.

The best accuracy and false alarm rate for a classification algorithm at the approaches suggested are calculated and plotted to create the ROC curve.

The Receiver Operating Characteristic curve, abbreviated ROC curve, was created to find hostile aircraft using radar. Therefore, option B is the correct option.
