A

Gradient descent minimizes cross-entropy by adjusting model parameters to increase the likelihood of the correct class predictions.

B

Gradient descent works by maximizing the cross-entropy loss, thus leading to poorer model performance.

C

The softmax function is unaffected by changes in model parameters during gradient descent.

D

Cross-entropy loss is only applicable for binary classification problems.

Understanding the Answer

Let's break down why this is correct

Gradient descent lowers the cross‑entropy loss by changing the model weights. Other options are incorrect because The idea that gradient descent increases the loss is a common mistake; Softmax does change when weights change.
