Storyline Multiple Choice any of several correct answers

Your biggest challenge will be exploring all possible combinations that make the answer correct and integrating them into the trigger's condition criteria.

If your question is not included in the Result slide, you don't need to disguise it as a Multiple Choice Question, as suggested by Judy. Instead, you can simply display the "Correct" or "Incorrect" feedback based on the conditions set in the trigger when the Submit button is clicked. 

If your question is included in the Result slide, then Judy's solution is the way to go. However, keep in mind that you’ll still need to create the logic and test all possible combinations to ensure the disguised question is marked as Correct when the condition criteria are met.

An example of a disguised question, and triggers with all possible combinations and conditions based on your initial post, would look like this:

You could trick the program by using a multiple-choice question that's hidden from the user. Then select the correct answer based on conditions that check what's selected among the multiple-response buttons. 

This post isn't directly about what you're trying to accomplish, but it does use a disguised multiple-choice question:

Not directly, but there's a work-around to this from back in the day that should still work for you. The trick is to ensure that the Scoring on the MCSA is set to Score by Choice (and not by Question).
