A Correct answer
Explanation

When a parent entity's key becomes part of the child entity's primary key, it creates an identifying relationship. The child entity cannot exist without the parent because its identity depends on the parent's key. In contrast, a non-identifying relationship would have the foreign key as a non-key attribute.
