DML - Data Manipulation language commands works on the data or values exists in tables. These are update, delete, insert.
DDL - Data Definition language commands works on the structure of the table such as rename columns, resize, adding or dropping new columns, add or dropping constraints on tables etc.

DDL commands are Create, alter, drop only.

Revoke and Grant command comes under DCL.
Update comes under DML. So answer should be 2, 3, 4.
How can any one say that answer would be 4 only? Can you explain this answer?
