Final answer:
In the revenue cycle, a participation association is observed between roles that interact in revenue-generating transactions. 'Customer and salesperson' is the correct pairing for such an association because they are directly involved in sales transactions contributing to the company's revenue.
Step-by-step explanation:
The question is asking which classes would have a participation association in the revenue cycle. A participation association is a concept where two classes are involved in a transaction or a series of events that are significant to the business process.
In the context of the revenue cycle, the classes that would be paired are typically those that interact directly as part of generating revenue for the company. After analyzing the options provided, A) Customer and salesperson would be an example of a participation association in the revenue cycle. This is because the customer and the salesperson are actively involved in the process of conducting a sale, which is a direct part of the revenue generation process.
Each of these roles is integral to the completion of a sales transaction where the customer acquires goods or services, contributing to the company's revenue. The salesperson is directly responsible for facilitating the transaction, often through the process of offering, negotiating, and closing sales, which inherently requires interaction with customers.
