  Explanation/Reference:

  From Java SE 8, we can use static and/or default methods in interfaces, but they should be non abstract methods. SO in this case using default in blank is completely legal. Hence option C is correct. Option A is incorrect as given method is not abstract, so can't use abstract there. Options B and E are incorrect as we can't have non abstract method interface if they are not default or static. httpsy/docs.oracle.com/javase/tutorial/iava/landl/defaultmethods.html
