When should Prototype pattern be used?

When objects need to be created in a step-by-step manner, allowing for more control over the object creation process
When the cost of creating a new object is high, and it is more efficient to create a copy of an existing object
When the number of objects in the system needs to be reduced, making it more efficient
When the objects in the system need to be loosely coupled, making the system easier to maintain and extend

Prototype pattern should be used when the cost of creating a new object is high, and it is more efficient to create a copy of an existing object. This pattern is useful for creating a large number of similar objects, as creating a copy is faster than creating a new instance from scratch.
