The correct option is stash. The git stash command is used to save changes that are not ready to be committed yet. It allows you to temporarily store your modifications and revert the working directory to match the last commit. This is useful when you need to switch branches or apply changes later.

Git's data model represents each commit as an independent snapshot of the entire project. This allows changes across branches to be isolated, and Git efficiently handles merging these snapshots during branch integration.

Git branches are a powerful feature that can significantly improve code quality. They enable developers to work on isolated features or fixes, reducing the chances of conflicts and making collaboration more efficient.

The correct option is 'merge.' In distributed teams, the 'git merge' command is used to integrate changes from different branches, ensuring that modifications are synchronized without overwriting each other's work. This command plays a vital role in collaborative development workflows.

In Bitbucket, the "Webhooks" feature is used for integrating with third-party services. Webhooks allow external systems to be notified of events in the repository, facilitating integration with services like CI/CD systems or issue trackers.

Merging changes from a Git Subtree involves using the 'git subtree merge' command. This command combines changes from the subtree repository into the main repository, maintaining history and avoiding unnecessary conflicts. Understanding subtree merging is vital for managing code modularization.

In Git, a tag is a reference to a specific commit. It is often used to mark a specific point in history, such as a release or a stable version. Tags are immutable and don't change with new commits.

The correct option is stash. The git stash command is used to save changes that have not been committed yet, allowing you to switch to a different branch or apply the changes later. It is useful for temporarily shelving changes.

In a large team setting, conflicts in Git are often resolved through a code review process before merging to the main branch. This involves team members thoroughly examining and validating the proposed changes in a collaborative manner. Code reviews help ensure that the code meets quality standards and does not introduce issues into the main codebase. This practice enhances code reliability and minimizes the chances of introducing bugs or conflicts during integration.

Git's decentralized nature allows parallel development, which enhances scalability for large teams. Developers can work independently, reducing bottlenecks and promoting efficient collaboration.

Option 3 suggests using GPG key-based commit verification, which adds a layer of security by ensuring the authenticity of commits. Other options may address different aspects of repository management but do not specifically enhance commit security through verification.

The git clone command is used to create a copy of an existing repository on your local machine. It not only copies the files but also sets up the necessary connections to the remote repository, making it easy to fetch updates.
