Which of the following is a valid example of a version control tool?

• A. Git
• B. Jira
• C. Jenkins
• D. Trello

Answer: (A)

Version control tools are used to track changes to a codebase over time, capture a history of edits, and support collaboration through branching, merging, and reverting changes. Git fits this purpose because it is a distributed version control system that records changes as commits, lets you create branches for new features, merge them back, and synchronize with remote repositories. This combination of local history and collaboration capabilities is what makes Git a version control tool. The other tools serve different roles: Jira handles issue tracking and project workflows, Jenkins automates builds and deployment pipelines, and Trello provides a visual board for organizing tasks. They help organize work or automate processes, but they aren’t used to version-control the actual codebase.
