C is the correct answer. tricky as method x() with weaker access is part of option B and not C.

answer : D class C implements interface A And method x() comes from class B abstract class B { public void x() {} public abstract void z(); } class C extends B implements A { public void z() {} } -------- C is wrong method x() in class C can not has weaker access privileges A and B are wrong too @Override on position 2 is not good There is no super class for class B
