Correct Answer: B
The result will be 'ab action'. The class Test implements both AbilityA and AbilityB. Despite the default method in AbilityA, the Test class provides its own implementation of the action() method. When the main method creates an instance of Test and calls the action() method through an AbilityB reference, the action() method in the Test class is executed, outputting 'ab action'.
