But what about A? It could add new columns without failing.

I think B is the best choice. It clearly indicates failure on new columns.

I thought D) none could work too, but I guess not.

I’m leaning towards "failOnNewColumns" too, but I wonder if "none" could be a trick option since it implies no action is taken.

I’m a bit confused; I feel like "addNewColumns" might also be relevant, but it doesn’t seem to align with the requirement to fail.

I remember practicing a similar question where we had to handle schema changes, and I think "failOnNewColumns" sounds right for this scenario.

I think the command should be something that explicitly fails on schema changes, but I’m not entirely sure which one it is.
