Solution
The main difference between a strong and weak entity lies in their dependency. A strong entity is an entity that can exist independently without relying on any other entities in a database. It has a primary key.
On the other hand, a weak entity is an entity that depends on another entity for its existence. It does not have a primary key of its own and uses a foreign key combined with its attribute to create a primary key.
So, the answer to your question would be c. Entity Primary Identifier. This is because the primary identifier (or primary key) is what distinguishes between a strong and weak entity. A strong entity has its own primary key while a weak entity does not.
