A team uses MBT for a web application with a model that includes multiple features. A change is made to the user authentication module, which is used by many other features. The team has limited time for regression testing. What is the most appropriate regression testing approach?

Skip regression testing and rely on the new test cases generated for the authentication change.

Run only the test cases that directly test the authentication module, as other features are unlikely to be affected.

Re-run the entire test suite to ensure no regressions, even though time is limited.

Prioritize test cases that cover the authentication module and its direct integrations, and run a subset of high-risk test cases from other features.
