c. Data Dynamic Language
d. Data Definition Language
e. Data Dynamic Logic

Answer 1

DDL stands for Data Definition Language, it is part of SQL used for defining and managing database structures with statements like CREATE, ALTER, and DROP.

Therefore, the correct answer is: option d). Data Definition Language

Step-by-step explanation:

In the context of SQL, data definition or data description language is a syntax for creating and modifying database objects such as tables, indices, and users.

DDL statements are similar to a computer programming language for defining data structures, especially database schemas.

DDL statements include CREATE, ALTER, and DROP which are used to create, alter, and delete database objects like tables, indexes, and users.

For example, the CREATE TABLE statement is used to define a new table in the database. Similarly, the ALTER TABLE command allows you to modify an existing table, and the DROP TABLE statement will completely remove a table and all its data from the database.
