Step-by-step explanation:
The question pertains to version control and the process that happens when Rob executes some action in a repository. The correct answer is B) Merge, alerted, resolution, manual. This means that, when Rob executes a merge operation, if a conflict is detected, he will be alerted, and the resolution of the conflict will be manual. Version control systems, such as Git, require the user to manually resolve conflicts that arise when merging branches with competing changes. This refers to the user being notified of conflicts in a version control system and resolving them manually. The user is typically notified of the conflict and must then choose which changes to keep before completing the merge process.
