MySQL Enterprise Backup records details of each backup in . . . . . . . .

Answer: Option B

This question is about MySQL Enterprise Backup, a tool that helps you create and manage backups of your MySQL database. It's asking where MySQL Enterprise Backup stores information about the backups it creates.
Let's break down the options:
* Option A: history_backup - This sounds like a plausible name for a table storing backup information.
* Option B: backup_history - This is another good possibility.
* Option C: backlog_history - "Backlog" usually refers to a queue of tasks. This doesn't seem directly related to backups.
* Option D: history_backlog - This combines the terms from Options A and C, making it less likely.
The most likely answer is either Option A or Option B. The actual table name might depend on the version of MySQL Enterprise Backup you're using.
