Which SQL command is used to remove a database?OptionsDROP DATABASEREMOVE DATABASEERASE DATABASEDELETE DATABASE

The correct SQL command used to remove a database is DROP DATABASE. Let's analyze why this is the appropriate choice:

1. DROP DATABASE: This command is specifically designed to delete a database and all of its contents permanently. Once you execute this command, the entire database structure, all tables, and the associated data are removed from the database management system.

2. REMOVE DATABASE: This is not a valid SQL command in standard SQL syntax.

3. ERASE DATABASE: Similarly, this command does not exist in SQL.

4. DELETE DATABASE: This is also incorrect since "DELETE" is typically used for specific records within a table rather than to remove a database as a whole.

Final Answer

The correct answer is: DROP DATABASE.
