You are developing a database using Microsoft SQL Server 2008. The database contains the tables shown in the exhibit. You are required to prevent parts from being deleted if they belong to a kit. If a part belongs to a kit, the delete should not occur and the IsDeleted column for the row should be changed to ‘True’. Parts can be deleted if they do not belong to a kit. You have the following Transact-SQL statement to be used in a trigger:

UPDATE p SET IsDeleted = 1 FROM KitPart kp
JOIN deleted d ON kp.PartID = d.PartID
JOIN Part p ON kp.PartID = p.PartID; DELETE FROM p FROM Part p
JOIN deleted d ON p.PartID = d.PartID
LEFT OUTER JOIN KitPart kp ON p.PartID = kp.PartID WHERE kp.KitID IS NULL;

You need to implement the Transact-SQL statement in a trigger.

Which trigger syntax should you use?

A.
CREATE TRIGGER tr_Part_d ON Part AFTER DELETE AS BEGIN
END

B.
CREATE TRIGGER tr_Part_d ON Part INSTEAD OF DELETE AS BEGIN
END

C.
CREATE TRIGGER tr_KitPart_d ON KitPart AFTER DELETE AS BEGIN
END

D.
CREATE TRIGGER tr_KitPart_d ON KitPart INSTEAD OF DELETE AS BEGIN
END
