I thought AnalyticDB was more for analytics rather than migration, so I’m leaning towards PolarDB or RDS.

Based on my understanding, PolarDB would be the most suitable Alibaba Cloud database for migrating from an Oracle database, as it is designed to be compatible with Oracle and supports many of the same features.

This question feels familiar! I think it is related to those practice questions we did on policy provisions. I want to say it's option B since it limits coverage, but I could be wrong.
