Step-by-step explanation:
The theory that best explains the emergence of Jeaneth and Delon's friendship is D. social exchange theory. This theory is predicated on the concept of mutual benefit through exchanges which can be material or nonmaterial, such as providing support or companionship.
Since Jeaneth is skilled with passengers and Delon is efficient in operations, they complement each other's abilities, creating a mutualistic relationship. In turn, this evolving partnership likely fosters trust and friendship, akin to instances where individuals cooperate in scenarios addressed by the prisoner's dilemma.
While the reward theory also seems pertinent because it focuses on the benefits individuals receive from relationships, the context given emphasizes the efficiency and effectiveness of their working relationship, which aligns more closely with the social exchange perspective. The social exchange theory recognizes the nonmaterial assets like friendship that may develop over time due to consistent and balanced exchanges.
