The general term for information about databases and the objects in MySQL is . . . . . . . .

This question asks about the term used to describe information about databases and the things inside them (like tables and columns).
Let's break down the options:
Option A: datum - A datum is a single piece of information. It's too specific for the question.
Option B: info - While "info" is short for "information", it's not a technical term used in databases.
Option C: record - A record is a row of data in a table, not information about the database itself.
Option D: metadata - This is the correct answer! Metadata means "data about data". It describes the structure and organization of your database and its objects.
So, the answer is Option D: metadata.
