A. B. C. D.B.
When you delete an object that is related to a junction object by a lookup relationship, the behavior depends on the configuration of the relationship and the settings selected for the relationship in the junction object.
A junction object is a custom object that has two master-detail relationships, each with a different object. The junction object creates a many-to-many relationship between the two objects, allowing multiple records from each object to be related to each other.
If the lookup relationship between the object and the junction object is set to "delete cascade", then deleting the object will automatically delete all related junction objects and any related master records. This means that option C is incorrect.
If the lookup relationship between the object and the junction object is set to "delete restrict", then the object cannot be deleted as long as there are related junction objects. This means that options A and D are incorrect.
If the junction object has a related field that is set to "delete cascade" or "delete restrict", then the behavior will depend on the settings selected for that field.
If the related field is set to "delete cascade", then deleting the object will also delete all related junction objects and any related master records. This means that option B is incorrect.
If the related field is set to "delete restrict", then the object cannot be deleted as long as there are related junction objects that have values in the related field. This means that options A, B, and D are incorrect.
In summary, the answer depends on the configuration of the lookup relationship and related field in the junction object. If the relationship is set to "delete cascade" or "delete restrict", the behavior will differ accordingly.
