git reset is for undoing uncommitted changes, but it isn't an option, next option will be git clean: https://www.atlassian.com/git/tutorials/undoing-changes https://www.atlassian.com/git/tutorials/resetting-checking-out-and-reverting

I agree with mutan. Correct answer is C. git revert only reverts already existing commits. https://git-scm.com/docs/git-revert/2.22.0#_description

I disagree with mutan and hythalo. Git checkout is used when you want to create a new branch or switch to another branch. By checking out will not affect any changes made in the file. git reset would have been the right answer, but it's not on the list. The closest answer to git reset is git revert. So option B is the CORRECT ANSWER.

Isn't the correct answer C? git revert only undos already commited changes.
