What are the limitations of using reflection?

  1. It can be used to change private fields to public

  2. It makes the application less secure

  3. It moves type checking to runtime, possibly leading to runtime errors

  4. All of the above

The correct answer is: It moves type checking to runtime, possibly leading to runtime errors

Reflection allows for access to private fields and methods, but it has limitations. While it can be useful for debugging and testing, it is not recommended to be used in production code. This is because it can compromise the security of an application by exposing private information that should not be accessed. Additionally, by shifting type checking to runtime, it can increase the chances of encountering runtime errors. Therefore, the correct answer is C, as A and B are specific examples of limitations that can arise from using reflection.
