Option A is probably the easiest solution, but I don't think it's the best one. Deploying Multi-Org with a single Marketing Cloud Account just seems like a recipe for disaster in this case.
Hmm, I'm torn between B and C. Deploying separate Publication Lists for each region seems a bit more complicated than necessary, but maybe it's the most foolproof way to ensure data integrity.
I was thinking of going with Option D, but now I'm not so sure. Separating regions into business units and applying Subscriber Filters could work, but it might be overkill for this scenario.
Option C looks good to me. Filtering data view permissions at the subscriber level seems like the most straightforward way to ensure data integrity across regions.
