What is one advantage of using Git as a version control system?

Using Git as a version control system provides the significant advantage that most operations are performed locally. This means that developers can perform tasks such as committing changes, viewing history, and creating branches without needing to connect to a central server. This local capability enhances the efficiency of development workflows, allowing for faster operations since they are not dependent on network connectivity. Furthermore, developers can work offline, making it easier to manage code changes in various environments and accommodating scenarios where internet access is limited or unreliable.

The other options highlight limitations rather than advantages of Git. For example, the notion of restricting development to single-user access contradicts the collaborative nature Git supports. Additionally, stating that changes must be made online overlooks the local functionality that Git provides, and suggesting that it is limited to small projects undervalues Git's scalability and versatility for handling complex, large-scale projects.
