The question asks which statement would remove the FOREIGN KEY constraint named FK_Emp_Dept from the Employees table.
Option 1: ALTER TABLE Employees DELETE CONSTRAINT FK_Emp_Dept; This uses a DELETE CONSTRAINT syntax, which is not a standard or widely supported command for removing constraints in major relational databases. Therefore, this would not work.
Option 2: ALTER TABLE Employees DROP CONSTRAINT FK_Emp_Dept; This is the typical syntax used in SQL Server and some other platforms to drop a named constraint from a table. It directly targets the constraint by name and removes it, fulfilling the goal of removing the FK constraint.
Option 3: ALTER TABLE Employees REMOVE CONSTRAINT FK_Emp_Dept; The REMOVE CONSTRAINT phrasing is not a valid SQL command across common RDBMSs for dropping constraints. It uses an incorrect keyword, so it would fail.
Option 4: ALTER TABLE Employees DROP FOREIGN KEY FK_Emp_Dept; In some systems like MySQL, you would drop a foreign key with a DROP FOREIGN KEY clause. However, the action requires the exact dialect syntax; since the provided answer aligns with the DROP CONSTRAINT form, this option may be correct in some DBMS, but not universally portable and not the form shown in the expected answer here.
Overall, option 2 is the correct choice for removing a named constraint in the context implied by the provided answer set, while the other options contain syntax that is invalid or not universally applicable for dropping a foreign key constraint.
