Explanation

Redis does support multiple logical databases within a single instance, numbered from 0 upward (defaulting to 16 databases, configurable via databases in redis.conf). You switch between them using the SELECT <index> command - for example, SELECT 1 moves you to database 1. Option B is incorrect because it contradicts this built-in Redis feature that has existed since the earliest versions. A helpful memory tip: think of Redis databases like numbered tabs in a spreadsheet - all within the same file (server instance), but each holds separate key spaces that don't interfere with one another.
