A Correct answer
Explanation

DML (Data Manipulation Language) statements are used to manipulate data within existing table structures. Modifying rows (using UPDATE, INSERT, DELETE) is DML operation. Adding a column is DDL (Data Definition Language) because it changes the table structure, not just the data. The question tests understanding of DML vs DDL distinction.
