Why each option
Entity relationship diagrams consist of entities, attributes, and relationships. Forks are a flowchart construct, not an ERD component.
Attributes are a core ERD component representing the properties or characteristics of an entity.
Relationships are a core ERD component that define how entities are associated with one another.
Forks are a component of flowcharts, not ERDs. An ERD models data structure using only three building blocks - entities (objects or concepts), attributes (properties of entities), and relationships (associations between entities). Forks have no role in ERD notation.
Entities are the primary building blocks of an ERD, representing real-world objects or concepts.
