Explanation

{"question_number": 8, "question": "Why is branching a core concept in Git?", "correct_answers": ["C"], "explanation": "Branching is fundamental to Git because it allows developers to create an isolated environment for new features, bug fixes, or experiments without affecting the stable main branch or other developers' work. This isolation is what makes parallel development possible - multiple team members can work on different features simultaneously. Option A describes merging, not branching itself. Option B is incorrect because Git branches are just lightweight pointers to commits, not physical file copies - this is one of Git's key performance advantages over older VCS systems. Option D describes directory organization, which has nothing to do with branching.", "generated_by": "claude-sonnet", "llm_judge_score": 3}
