I definitely recall that PolarDB supports MySQL and PostgreSQL, but I can't remember if MongoDB was included or not.

I feel like I saw something about Oracle not being compatible with PolarDB, but I could be mixing it up with another database.

Easy peasy! PolarDB is a PostgreSQL-compatible database, so it definitely supports PostgreSQL. The other options are all different database engines, so the answer has to be C, MySQLo.

Okay, I've got this. PolarDB is an Alibaba Cloud database service that's compatible with PostgreSQL. So the answer has to be C, MySQLo, since that's a different database engine that PolarDB wouldn't support.

Hmm, I'm a bit confused on this one. I know PolarDB is a PostgreSQL-compatible database, but I'm not sure about the other engine support. I'll have to think this through carefully and review my notes before answering.

I'm pretty sure PolarDB supports Oracle, so I'll eliminate that option. MongoDB is a NoSQL database, so that's probably not supported either. I think the answer is C, MySQLo, since PolarDB is a relational database and wouldn't support a non-relational engine like that.

Haha, the answer is definitely B. MongoDB. I mean, who even uses MongoDB with PolarDB? That's like trying to fit a square peg in a round hole.
