Hi @Samirah,

Thanks for the question! (A) is wrong because it introduces this concept of importance when it says “more important.” The stimulus doesn’t say anything about that, so a concept about importance can’t be a principle that the reasoning is based on.

Hope this helps! Feel free to ask any other questions that you might have.
