Final answer:
Version control systems indeed create a change set or commit, which is a collection of code changes that help track modifications, collaborate, and revert to previous versions when necessary.
Step-by-step explanation:
True, version control systems establish a change set as part of their primary functionality. A change set, also known as a commit, is a collection of changes such as additions, deletions, and modifications made to the source code in a repository. When a developer makes changes to code, these alterations are grouped into a change set which documents the specific differences from the previous version, allowing for easier tracking of changes, collaboration among multiple developers, and the ability to revert back to previous versions if necessary.
