Answer
Prototype loses its scope. Frame the concept in practical terms so you can explain it during interview discussion.
The main drawback is that the Prototype bean effectively becomes a Singleton, defeating its purpose of providing a new instance with each use. This can lead to unexpected shared state if the Prototype beans are stateful. For instance, a Prototype bean designed to hold user session data will not work correctly if used directly in a Singleton service, as all users will share the same instance.
