b-Storage definition language is used to specify the internal schema.
c-Storage definition language is used to insert, delete, and update data.

Answer 1

The incorrect statement is that storage definition language is used to insert, delete, and update data.

Step-by-step explanation:

The correct answer is c-Storage definition language is used to insert, delete, and update data. Storage definition language (SDL) is not used to manipulate data in a database. Data definition languages (DDL) are used by DBAs and database designers to define the database schema and structure. On the other hand, storage definition language (SDL) is used to specify the physical storage and organization of data within a database.
