A

Hinge Loss

B

Logistic Loss

C

Neyman-Pearson Loss

D

Cross-Entropy Loss

Understanding the Answer

Let's break down why this is correct

This loss pushes the score of the correct class higher than the others by a fixed margin. Other options are incorrect because Many think logistic loss can create margins, but it only measures how well the model predicts probabilities; Neyman‑Pearson loss is about controlling one type of error, not about separating classes.
