Final answer:
The female salesperson should always sit next to the Decision-maker; a salesman should always sit next to the customer.
Step-by-step explanation:
The correct answer is b. Decision-maker, customer.
The question is related to the seating arrangement for salespeople. It states that the female salesperson should always sit next to the decision-maker, and a salesman should always sit next to the customer. This arrangement helps avoid any potential concerns related to relationships.
For example, if a female salesperson is pitching a product to a decision-maker who is also a customer, it would be appropriate for her to sit next to that person. Similarly, a male salesman would sit next to a customer who is not the decision-maker, so as to maintain a professional boundary.
