What operation does Dave need to perform to keep the rest of the User Story intact while removing a custom field?

To understand why the correct answer involves recomitting files in a Git operation, it's important to recognize the mechanics of version control and how changes are managed within a User Story. When Dave needs to remove a custom field but wishes to maintain the rest of the User Story intact, he must ensure that the changes he makes do not disrupt the existing structure or content of that User Story.

The recommit files Git operation allows Dave to modify the current state of the project by making specific changes, such as removing the custom field, while preserving all other components of the User Story. This operation effectively updates the project to reflect the removal, while still keeping the other elements intact and functioning as intended.

In contrast, recreating the feature branch would effectively create a new branch from the current state, which could lead to additional complexities and might not retain the current version's history in a way that cleanly addresses the desired change. Similarly, a remove commit operation would not be appropriate for selectively removing only the custom field, as it would imply reverting back to an earlier state entirely rather than adjusting the specific part that needs updating. Deleting the User Story would of course eliminate it completely, which is not the goal when only a minor adjustment is necessary.

Thus, the option that
