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.

Hmm, I think it's gotta be B. MongoDB, right? PolarDB is all about the relational databases, not the NoSQL ones.

I'm not sure, but I think PolarDB does not support MongoDB because it is a NoSQL database.

Reuben: Exactly, mixing in a NoSQL database like MongoDB would be strange.
