### Break Down the Problem
1. Identify the elements that are part of ER (Entity-Relationship) diagrams.
2. Determine which option does not belong in the context of ER diagrams.

### Relevant Concepts
1. **Entity**: Represents a real-world object or concept.
2. **Relationship**: Depicts the connection between entities.
3. **Attribute**: A property or characteristic of an entity.
4. **Primary Key**: A unique identifier for an entity in a database.

### Analysis and Detail
1. **Entities** are essential components of ER diagrams.
2. **Relationships** illustrate how entities interact.
3. **Attributes** provide details about entities.
4. **Primary Key** is crucial for identifying unique records but is not typically represented as an overarching part of the ER diagram structure like entities, relationships, and attributes are.

### Verify and Summarize
- Upon assessing the components, "Primary Key" is an important aspect of relational databases but is not a fundamental part of ER diagrams itself.

### Final Answer
**d. Primary Key**
