Answer 1

A weak entity has a primary key that is partially or entirely generated from the relationship's parent entity.

An entity type should contain a key attribute that uniquely identifies each entity in the entity set, although certain entity types do not have a key attribute. These are known as Weak Entities.

Entity sets with insufficient properties to generate a primary key are referred to as weak entity sets, whereas entity sets with a primary key are referred to as strong entity sets. Because the weak entities lack a primary key, they cannot be recognized on their own and must rely on another entity (known as owner entity).

Hence, the correct option is weak entity.
