When multiple README files exist in different locations within a GitHub repository, the README.md file located in the root directory of the repository will be displayed first by default. This file serves as the main documentation for the repository and is automatically rendered on the repository's home page.
Root Directory:
Option C is correct because the README.md file in the root directory is prioritized and displayed first on GitHub. This is the standard behavior for how GitHub presents documentation.
Incorrect Options:
Option A (.github) is incorrect because while a README.md file in the .github directory might be used for certain configurations, it is not the first to be displayed.
Option B (/src) is incorrect because the README.md in the src directory is not prioritized over the root.
Option D (/docs) is incorrect because documentation in the /docs folder is typically secondary to the root README.md.

The primary purpose of creating a security policy in a GitHub repository is to guide users and contributors on how to report security vulnerabilities in a responsible and secure manner. This policy outlines the preferred method of communication, timelines, and any other pertinent information related to handling security issues.
Security Policy:
Option C is correct because a security policy provides guidelines for responsibly disclosing security vulnerabilities. This helps maintainers respond to and address security concerns promptly and securely, thereby protecting the project and its users.
Incorrect Options:
Option A is incorrect because ensuring peer code review is a best practice for code quality, but it is not the primary purpose of a security policy.
Option B is incorrect because push protection for secrets is managed through repository settings, not the security policy.
Option D is incorrect because customizing Dependabot configuration is related to dependency management, not directly to security policies.

A GitHub repository serves as a collaborative space where developers can share and manage code files, track changes, and store revision history. It is much more than just a folder or simple tool; it is a comprehensive version control system that allows teams to collaborate effectively on codebases. Repositories enable developers to work together, manage contributions, review code, and maintain a complete history of every change made to the project.

GitHub Sponsors allows developers and organizations to financially support open-source contributors directly on the GitHub platform.
Setting Up a Sponsored Developer Profile:
Option D is correct because before a contributor can receive funding through GitHub Sponsors, they need

Pull requests (PRs) on GitHub can have several statuses that indicate their current state in the development and review process:
Draft:
Option A is correct. A pull request can be in a "Draft" status, indicating that it is a work in progress and not yet ready for review.
Closed:
Option B is correct. A pull request can be "Closed" without being merged, which might happen if the proposed changes are not needed or are incorporated differently.
Merged:
Option D is correct. A pull request that has been reviewed and approved can be "Merged" into the target branch, indicating that the changes have been successfully incorporated.
Open:
Option F is correct. An "Open" pull request is one that is active and awaiting review or further action.
Incorrect Options:
Option C (Rebasing) is incorrect because "Rebasing" is not a status; it's an operation that can be performed on branches.
Option E (Modified) is incorrect because there is no "Modified" status for pull requests.
