  1. Data Definition Language
  2. Data Manipulation Language

  4. All of the above are languages.
Explanation
Answer: D - Data definition, data manipulation, and query are all database languages. Data definition languages (DDL) define the structure and schema of the database. The structure could mean the table size, key placement, views, and data element relationship. The schema describes the type of data that will be held and manipulated and its properties. Data manipulation language (DML) contains all the commands that enable a user to view, manipulate, and use the database. Query language (QL) enables users to make requests of the database.
