Which of the following can be performed within GitHub Mobile?
GitHub Mobile provides a streamlined experience for managing your GitHub notifications and participating in discussions, but it does not offer full functionality compared to the desktop or web interface.
Managing Notifications:
Option E is correct because GitHub Mobile allows users to manage notifications, keeping them up to date with their repositories, issues, pull requests, and other activities on GitHub.

What is the purpose of GitHub Sponsors?
GitHub Sponsors is a program designed to provide a platform for developers and companies to financially support open-source projects and their maintainers.
Financial Support for Open Source Projects:
Option D is correct because the main purpose of GitHub Sponsors is to allow members of the developer community, including individuals and organizations, to financially support open-source projects and maintainers. This helps sustain open-source development by providing developers with the resources they need to continue their work.

GitHub Copilot is described as an AI pair programmer that offers autocomplete-style suggestions. It is a tool integrated into development environments like Visual Studio Code that helps developers by providing code suggestions as they type. Copilot can suggest entire lines or blocks of code based on the context of what you're writing, making it a valuable assistant in coding, but not a replacement for developers.
From the Organization settings, which restrictions can organization owners place on GitHub Actions usage?

Which of the following statements most accurately describes who can access a private repository Wiki?
For private repositories on GitHub, the Wiki is accessible to anyone who has Read access to the repository.
