Which of the following situation requires the use of ID-dependent entities?
Answer: D
Correct answer: All of the above use ID dependent entities
An ID-dependent entity cannot exist without its parent and takes the parent’s identifier as part of its own. All three cases have that character: an association relationship carries data of its own on an intersection between two parents, a multivalued attribute becomes a table dependent on the entity it describes, and an archetype and its instances stand in the same relation.
