What problem arises when using generics to perform operations on generic types?

  1. Type erasure

  2. Type extension

  3. Type confinement

  4. Type expansion

The correct answer is: Type erasure

When working with generics, the problem of type erasure can arise. This occurs when the generic type is replaced by its upper bound type at runtime, resulting in the loss of type information. This can lead to issues when trying to perform operations on the generic type, as the specific type information is no longer available. Types B, C, and D are incorrect because they are not related to the specific problem of type erasure when using generics. They are not terms commonly used in reference to generics or their functionality.
