Hi there. I'm truly confused about this question even if I have scanned the possible right explanations from other platform.

Each of them emphsized on the different points. So, I want to hear some advice from 7sage on why C is the correct answer.
BTW, as a non-native ENGLISH speaker, I'm also confused by the question stem. Is it asking us to weaken the content of the recommendation or asking us to weaken the act of giving the recommendation?
