The ER (Entity-Relationship) model is a data model that describes the data or information aspects of a business domain or its process requirements, in an abstract way that lends itself to ultimately being implemented in a database such as a relational database.

Here's how you might match each element of the ER model to the term which best describes it:

1. Employees: This is an entity. An entity is a thing or object in the real world that is distinguishable from all other objects. For example, each employee of a company is an entity.

2. ssn: This is an attribute. An attribute is a property or characteristic of an entity. For example, the social security number (ssn) is an attribute of the employee entity.

3. pname: This is also an attribute. It could represent the name of a project or a policy, depending on the context.

4. age: This is another attribute. It could represent the age of an employee or a dependent.

5. Dependents: This is another entity. Each dependent of an employee is a separate entity.

6. Policy: This could be an entity or an attribute, depending on the context. If it represents a specific policy that an employee has, it's an entity. If it represents the type of policy that an employee has, it's an attribute.

7. cost: This is an attribute. It could represent the cost of a policy, for example.
