The wording of the question is a little complex, but looking at the answers we can eliminate the wrong ones and quickly mark the right option which is the letter A. An abstract class, unlike an interface, can exist without any abstract method, but when reading the question needs to have at least one abstract method to work correctly, eliminating options B and C. The "printToy" method doesn't need to be abstract because it can sell a toy without a description, but we can't sell a toy without a price so the only method that needs to be abstract is the "calculatePrice". Which indicates that the correct answer is the letter A.
