DML refers to SQL keywords that:

• A. A set of SQL keywords that create tables only
• B. Data Manipulation Language for retrieving or changing data
• C. Data Definition Language for defining database schemas
• D. Data Control Language for managing permissions

Answer: (B)

DML is the part of SQL that works with the data itself in the tables: retrieving data and making changes to existing data. It covers operations like SELECT to read rows, INSERT to add new rows, UPDATE to modify existing ones, and DELETE to remove rows. It assumes the database schema is already in place and focuses on manipulating the records, not the structure of the tables. Creating, altering, or dropping tables belongs to Data Definition Language, which defines the database schema. Managing who can access data (permissions) falls under Data Control Language. So the description of DML as handling retrieving or changing data is the best fit.
