A developer is working on an enhancement for an application feature and has made changes to a branch called ‘devcor-432436127a-enhance4‘. When merging the branch to production, conflicts occurred. Which Git command must the developer use to recreate the pre-merge state?

When a git merge operation results in conflicts, Git pauses the process, leaving the repository in a special "merging" state. The developer must manually resolve the conflicts before committing. If the developer decides to abandon the merge attempt entirely, the git merge --abort command is used. This command aborts the conflict resolution process and restores the repository and working directory to the state they were in just before the merge was initiated.

A. git merge -no-edit is incorrect because it is used to accept the auto-generated merge commit message without opening an editor. It does not abort a merge with conflicts.
C. git merge -revert is incorrect because -revert is not a valid option for the git merge command. git revert is a separate command used to undo a previously committed merge.
D. git merge --commit is incorrect because this is the default behavior to finalize a successful merge by creating a merge commit. It cannot be used when conflicts are present.

you can do that with git merge --abort."
