Answer 2

Answer:

An ID-dependent entity refers to an entity that joins the identifier of one entity to the identifier of another entity.

Strong entity always has a primary key.The weak entity has a foreign key referencing the primary key of the strong entity.The weak unit is dependent on the strong unit.The strong entity is independent of the rest of the entities.
