 answer is Private

becoz there is no meaning in declaring interface methods as private.

As interface methods are implemented in inherited classes only.

D is the correct choice

Virtual keyword is meaningful when the derived class is expected to override base class method. Here a class will 'implement' a method of an interface, hence virtual is not meaningful for interface methods.

Static keyword indicates that a method or field is common to all instances of a class. For an interface there will not be any instance, hence static is not meaningful.

An interface and all its methods must be declared public for enabling classes to implement them.

interface-modifier:
     new
     public
     protected
     internal
     private

the above are valid interface access modifiers, however some are only allowed in certain circumstances. Check out C# spec or Anders book on C# (see below).

So the answer is "the question is incomplete or vague"

All interface members implicitly have public access. It is a compile-time error for interface member declarations to include any modifiers. In particular, interfaces members cannot be declared with the modifiers abstract, public, protected, internal, private, virtual, override, or static.

You decide.

Interface members are public by default. But we dont/cant specify modifiers to them so that we dont fall into the impression that thay can also be private or ..... They are public by default and we dont have to specify that!
