The correct options are BFG Repo-Cleaner and git filter-branch.

The BFG Repo-Cleaner is a purpose built tool that rewrites Git history to remove files and sensitive data. It is designed to be fast and simple for whole repository cleanups and is often the easiest choice when you need to purge keys or large files from many commits.

The git filter-branch command is a built in Git mechanism that can apply filters to every commit so you can remove a file from the entire history. It is flexible and powerful but it is slower and more complex than modern alternatives and the Git project now recommends tools like git filter-repo for heavy or scripted rewrites.

Both tools rewrite commit history so you must force push the cleaned branches and coordinate with your team so everyone reclones or resets their local repositories to avoid divergent histories.

The Google Cloud Source Repositories option is incorrect because a hosted repository service does not by itself remove a file from past commits. You still need a history rewriting tool to purge the file and then push the cleaned history back to the host.

The git rebase option is incorrect because rebase is intended for editing or replaying commits in a linear history and it is not practical for purging a file across an entire repository or across many branches. It can handle small manual edits but it does not scale for complete history cleansing.
