d. To define the structure of the database
Data Definition Language (DDL) in DBMS is used to define the structure of the database such as defining tables, views, indexes, constraints, etc. It allows users to create, modify, and delete database objects and their attributes. It is used to specify the data types, relationships, and other constraints that should be applied to the data in the database.
