Answer:
D) The negotiator role
Step-by-step explanation:
Business managers often have to negotiate with suppliers, employees or in this the landlord in order to solve a potential conflict, lower costs or maximize revenues. When two parties negotiate, they both seek to maximize their own benefit, so a negotiation process can either result in a better or worse position for the company.
In this particular case, Marvin negotiated with his landlord in order to lease another floor of the building at a lower than market cost which benefits the financial situation of the restaurant. He did a good job and was a good negotiator since his company will benefit from this negotiation process.
