Show answer & explanation
Correct answer: A
The correct answer is DML (Data Manipulation Language). DML includes commands such as SELECT, INSERT, UPDATE, and DELETE, which allow users to query data and perform operations like inserting, modifying, and deleting tuples in the database. DDL (Data Definition Language) is used to define the database structure using commands like CREATE, ALTER, and DROP. It does not support data manipulation operations. A query is a request to retrieve data, but it is not a full language. It does not include commands for inserting, deleting, or modifying data. A relational schema defines the structure of the database, including tables and their attributes. It does not allow data manipulation operations.
