DML is short name of Data Manipulation Language which deals with data manipulation and includes most common SQL statements such SELECT, INSERT, UPDATE, DELETE etc, and it is used to store, modify, retrieve, delete and update data in a database not manipulate database structure.
But it is database structure manipulation, means schema, database properties, table properties etc... option "A" is correct
For data manipulation, it should be DML. DDL is for the definition of data. The answer should be DML.
Yes your discussion is right but for manipulation we need DML......not DDL
why option C is not the answer?
