Thank you for the opportunity to help you with your question!

This is a rule of product question . The correct answer is 81 different ways thus B is the correct answer . To state it simply if you have a ways to select something from a set , and b ways to select something from another set you have a * b ways for both . It applys for any given number of sets . In this case its 3 * 3 * 3 * 3 = 81

Please let me know if you need any clarification. I'm always happy to answer your questions.
