What does reflection allow you to do with classes?

Modify the source code at runtime
Dynamically call methods that are not known at compile time
Increase the efficiency of method calls
Decrease runtime of the application

The correct answer is: Dynamically call methods that are not known at compile time

Reflection allows you to dynamically access and invoke methods in a class, even if the methods are not known at compile time. This is not possible with the other options. Option A refers to modification of source code, which is not related to reflection. Option C mentions efficiency, which is not directly related to classes. Option D refers to the runtime of the application, which is also not directly related to reflection.
