According to the ER diagram, the relationship between customer and employee is represented by a solid line with a crow's foot on the customer side, indicating a many-to-one relationship. This means each customer can be served by at most one employee, and each employee can serve multiple customers. Therefore, option C "Each customer is served by exactly one employee" is true, while options A, B, and D are not supported by the diagram.
