Explanation

Option B is correct because the statement has the storage types reversed. Game rankings, which require fast, frequently-updated sorted data, are best suited for a cache database (such as Redis, which offers sorted sets ideal for leaderboards) - not a document database. Conversely, user and player information like equipment and points is persistent, structured data that should be stored in a document database (or relational database), not in cache, because cache is volatile and not designed for long-term data retention.

Option A is wrong because it accepts the reversed mapping as correct, which would lead to rankings being stored inefficiently in a document database and user data being lost when cache expires or resets.

Memory tip: Think "rankings are temporary and fast, so cache; player profiles are permanent, so database." If the statement swaps these, it is false.
