Which modifier can be applied to an abstract interface method?
D.
All abstract interface methods are implicitly public, making Option D the correct answer.
Option A is incorrect because protected conflicts with the implicit public modifier.
Since static methods must have a body and abstract methods cannot have a body, Option B is incorrect.
Option C is incorrect.
A method, whether it be in an interface or a class, cannot be declared both final and abstract, as doing so would prevent it from ever being implemented.
