The correct option is Open the GitHub website then click the plus icon in the upper right and choose New repository and complete the form and create it.

This creates a brand new empty GitHub repository that is owned by her account and is neither a fork nor a clone. She can choose the repository name and visibility and optionally initialize with a README or keep it empty. GitHub will then provide the remote URL that she can use to connect a local project or she can push an existing local repository to it.

Run git checkout -b new_app in an existing local repository to make a new remote repository automatically is incorrect because this command only creates a new local branch. It does not create a new repository on GitHub and it does not set up a remote.

Copy the URL of another repository and run git clone to create the project folder is incorrect because cloning copies an existing repository and sets the origin to that source. It does not create a new empty repository under her account and it is not independent of the original.

Use Google Cloud Source Repositories to host the project is incorrect because the question requires a repository under her GitHub account and this is a different hosting service. This service has been retired by Google and is less likely to appear on newer exams.
