A

Cross-Entropy Loss

B

Hinge Loss

C

Mean Squared Error

D

Focal Loss

Understanding the Answer

Let's break down why this is correct

Focal Loss is a special version of cross‑entropy that adds a factor to reduce the weight of easy examples. Other options are incorrect because Many people think the usual loss for classification is the best choice; Hinge Loss is used in support vector machines to maximize a margin.
