In Aggregation, do the part and the whole survive independently?

In Aggregation, do the part and the whole survive independently?

• A. No
• B. Not necessarily
• C. Yes, they survive independently
• D. Only when both are stored together

Answer: (C)

Aggregation describes a loose has-a relationship where lifecycles are separate. In this setup, the part can exist even if the whole is gone, and the whole does not manage the part’s destruction. Think of a Team and its Players: players can exist outside a specific team and may move between teams over time. If the team is dissolved, the players still exist. This shows that the part’s existence isn’t bound to the whole, which is why they can survive independently. So, the best answer reflects that independence of lifecycles in aggregation.
