What is the main difference between classification and regression in supervised learning?

Classification predicts continuous values, while regression predicts discrete values.

Regression is used for categorical data, while classification is used for numerical data.

Classification focuses on binary outcomes, while regression focuses on multi-class outcomes.

Classification deals with defined labels, while regression deals with continuous values. (correct)
