In the context of owner and weak entity sets in the ER (Entity-Relationship) data model, which one of the following statements is TRUE?

In an Entity-Relationship (ER) model:

• A weak entity set is an entity set that does not possess sufficient attributes to form a primary key on its own. It relies on an identifying (owner) entity set for identification.

• Each weak entity must be associated with an owner entity to be uniquely identified. Consequently, the weak entity set MUST have total participation (existence dependency) in the identifying relationship set.

• The owner entity set, however, can contain entities that do not associate with any weak entity, meaning its participation in the identifying relationship is typically partial.

Hence, statement (A) is TRUE.
