Answer 2

The answer is D because the main purpose of SQL is to create a database where you pass some data. For passing those data we define data structures. DDL commands are the commands that are used to create or define a table structure which are Create, Alter and drop a table. On the other hand, DML commands are used to change and manipulate the preexisting data in the table.
