Final answer:
The relationship between a sports team and the players, coaches, and sponsors is an example of aggregation, as the parts can exist independently of the whole.
Step-by-step explanation:
A relationship between a "sports team" and its players, coaches, and sponsors can best be described using the concept of aggregation in object-oriented programming (OOP). Aggregation is a type of association that implies a whole/part relationship where the part can exist independently of the whole. For instance, players, coaches, and sponsors are individually complete and can exist independently of a sports team. If the sports team dissolves, the players, coaches, and sponsors continue to exist.
