static members, and non-static inner classes cannot have static members. So A, B wrongTwo. A non-static member of a static inner class can access a static variable of an external class and cannot access a non-static variable of the outer class; return d1 error.So D wrongThree. Non-static members of non-static inner classes can access non-static variables of the outer class. So C is correctFour.
