In GitHub Flow, creating a new branch is a key step in the development process that allows for isolated development of new features or fixes without affecting the main codebase.

Experimenting with New Features or Fixes:

Option C is correct. The primary purpose of creating a new branch in the GitHub flow is to provide a safe space to experiment with new features or fixes. This allows developers to work on changes independently and only merge them into the main branch after they have been reviewed and approved.

Incorrect Options:

Option A (To create a backup of the main branch) is incorrect because branches are not typically used for backups; they are for active development.

Option B (To capture information about an issue) is incorrect because issues are tracked separately; branches are for code changes.

Option D (To incorporate changes from a review) is incorrect because incorporating changes is done during the pull request process, not when creating a branch.
