Which three of the following metrics can be tracked using repository insights?

Repository insights provide maintainers with visual and analytical information about repository activity and health. Pull request activity can be reviewed to understand collaboration patterns, review activity, and changes over time. Contributions over time are also available through repository insights, helping maintainers see how actively people are contributing to the project. Security vulnerabilities in dependencies can be surfaced through security-related views such as dependency alerts and related repository security information. Team synchronization status and repository visibility settings are administrative or configuration-related items, not repository insight metrics. Issue resolution rates may be useful in project reporting, but it is not one of the selected repository insights metrics in this question. These insights help teams monitor repository progress, collaboration, and risk.
