Correct Answer: C. c) DDL (Data Definition Langauge)
Explanation: DML (Data Manipulation Language) is the language component responsible for manipulating data within a database. This includes the operations you mentioned:
Querying data: Retrieving information from the database.
Inserting data: Adding new records to the database.
Deleting data: Removing existing records from the database.
Altering data: Modifying the values of existing records.
Brief overview of other options:
DDL (Data Definition Language): Defines the structure of the database, including creating, modifying, and dropping tables, indexes, and other database objects.
DCL (Data Control Language): Deals with access control to the database, granting or revoking privileges to users.
TCL (Transaction Control Language): Manages the integrity and consistency of data through transactions (commit, rollback, savepoint).
So, DML is the correct choice for performing actions on the data itself.
