Please select the best answer choice from A-D below. When an anonymous class accesses a local variable from the method that the anonymous class is created inside, why must the variable be marked as final?

A.Until the variable is marked as final, the Java compiler will assume that the programmer not is finished editing the code. It is a compile error to compile incomplete code.

B.It is an error for an anonymous class instance to change the value of a variable that is not inside the class. If the variable is not marked final, the instance may be able to change it and cause the method to not run properly.

C.All local variables are stored on the stack, but the anonymous class instance is in the heap. The stack variable may not exist when the anonymous class needs it. By indicating that the variable is final, the compiler knows that the value will not change and so it can make a copy for the anonymous class.

D.Anonymous classes, because they do not have a name, are static classes. Therefore, all variables that the class accesses must be either static or final.
