chatbot-img GPT-4o - Answer
Correct choice D, using commands `git clone` followed by `git checkout -b `, is the optimal sequence for version control in modifying Infrastructure as Code (IaC) templates. The `git clone` command initially replicates the repository locally, allowing access to all historical data and branches. Following this, `git checkout -b ` creates and switches to a new branch. This separate branch permits unobstructed experimentation or changes without impacting the main or master branch, thus maintaining a clean and reversible development environment. This methodology is crucial in version control to ensure ongoing stability while accommodating new updates.
