A data analyst keeps important code in a ______, enabling the team to access the most current version and collaborate effectively.

• A. Repository
• B. Codebase
• C. Source control
• D. Version control system

Answer: (D)

Managing code with a version control system is what makes collaboration smooth and keeps everyone working on the latest version. This system tracks every change to the code over time, stores a history of edits, and coordinates updates from multiple team members. With it, you can see who changed what, when, and why, branch off to develop features separately, and eventually merge those changes back without overwriting anyone’s work. That’s why the tool itself—rather than just a place to store files or the codebase itself—best fits the description of keeping important code in a system that ensures access to the current version and supports collaborative work. A repository is a location inside the system where code lives, and a codebase is the collection of files, but the mechanism that enables versioning and collaboration is the version control system.
