The data manipulation language (DML) of SQL contains SELECT, INSERT, DELETE, and UPDATE statements, whereas the data definition language (DDL) of SQL contains CREATE, , and DROP statements. (one word, case insensitive, zero point if misspelled)

"Alter" is the correct answer for the above question.

Explanation:

The DML is a type of SQL command which is used to manipulate the data of the table, it can create or delete or update the data. It holds the command delete, insert, update and select which is mentioned on the question.The DDL is a type of SQl command which is used to define the table and database. It collects the list of command of Alter, create and drop, in which the drop and create are listed in the question but the alter is missing. Hence alter is the correct answer.
