I'm not sure, but I think it might also be C) The proportion of events in the training data.

I agree with Donte, as you move along the curve, the probability cutoff for scoring changes.

I think it's the proportion of events in the training data that changes as you move along the ROC curve. The more events you have, the better your model can discriminate between positive and negative cases.

The ROC curve shows the trade-off between the true positive rate and the false positive rate, so as you move along the curve, the probability cutoff for scoring must be changing. I'm pretty sure that's the right answer.
