The correct answer is B. squash.
Squash is a Git command that merges multiple commits into a single commit. This can be useful if you have made multiple commits for a single change, or if you want to clean up your commit history.
To squash commits, you can use the git squash command. For example, to squash the last two commits in your current branch, you would use the following command:
git squash HEAD~2
This would create a new commit that contains the changes from the last two commits, and the original commits would be deleted.
You can also squash commits interactively. To do this, use the git squash --interactive command. This will open a text editor with a list of the commits that you can squash. You can then select the commits that you want to squash, and enter a message for the new commit.
Squash is a powerful tool that can be used to clean up your commit history and make it easier to read. However, it is important to use it carefully, as it can be difficult to undo changes that have been squashed.
