The correct option is Create a public repository named exactly the same as your GitHub username and add a README.md in the root.

GitHub recognizes a public repository whose name exactly matches your username and automatically renders its root README at the top of your profile. The repository must be public and the README.md must be in the root of the default branch. After you push the file, the content appears on your profile without any further configuration.

The option Enable GitHub Pages on any repository is incorrect because Pages publishes a static site from a branch or folder and it does not control the profile header. Enabling it does not create or display a profile README.

The option Rename a README file to your username in any repository is incorrect because the feature depends on the repository name rather than the file name. Changing a filename alone will not make GitHub show it on your profile.

The option Create a repository named profile and put a README in it is incorrect because the repository must be named exactly your username. A repository named profile will be treated like any other repository and will not drive the profile README.
