_______ command is used to remove a relation from SQL database.

Answer: DROP TABLE

Explanation: The DROP TABLE command removes the table definition and all its data from the database.

• Syntax example: DROP TABLE table_name;

• DELETE removes rows from a table (e.g., DELETE FROM table_name WHERE ...), but does not remove the table structure.

• There is no standard SQL command named "REMOVE TABLE"; use DROP TABLE to remove the table itself.

• UPDATE changes existing rows and does not delete the table.

• Note: DROP TABLE is a DDL operation. Depending on the DBMS and transaction settings, it may not be reversible.
