TheCODEOWNERSfile in a GitHub repository is used to define individuals or teams that are responsible for specific parts of the codebase. When changes are made to files or directories that match the patterns specified in theCODEOWNERSfile, GitHub automatically requests reviews from the listed code owners.
* Setting Reviewers Automatically:
* Option Dis correct because the primary purpose of aCODEOWNERSfile is to automatically set reviewers for pull requests that affect the specified files or directories. This ensures that the appropriate team members are notified and review the changes before they are merged.
* Incorrect Options:
* Option Ais incorrect because theCODEOWNERSfile does not restrict who can edit specific files; it only influences who is required to review changes.
* Option Bis partially related but not fully accurate because whileCODEOWNERSdoes require certain reviews, it does not mandate peer review for all code changes.
* Option Cis incorrect because theCODEOWNERSfile does not define access permissions for the repository; it deals with code review processes.
