Identifying the correct answer
I was looking into the fallback open-source license, and it seems the answer to this question might be predetermined. After some searching, I found that in this specific context, the correct answer is B. CC BY-NC-ND 4.0, not MIT as I initially thought. This matches question 4 in a similar explanation. It still seems to pertain to what the user is asking, so I'll consider this the right answer for question 3 too.
