Which concept describes a separate line of development to keep experiments separate?

• A. Repositories
• B. Branch
• C. Commits
• D. Tags

Answer: (B)

Branching is the way to keep experiments separate by creating a parallel line of development within the same project. A branch acts as a lightweight pointer to a sequence of commits, so you can work on new ideas, tests, or features without touching the main line. You can switch to the branch, make changes, run tests, and iterate freely. When the experiments are ready, you merge the branch back into the main line, bringing over the changes in a controlled way. This isolation is what makes branching ideal for trying out ideas without risking the stability of the primary codebase. In contrast, a repository is the whole project storage, commits are individual changes, and tags are markers for a specific point in history rather than ongoing development lines.
