Although I have intution that the word "many" in Answer (C) is too strong, I remember one of foundational course said that "many" implies "some." Can someone help me how to reconcile those two ideas?

I'm a bit confused about option D. The video explains that option D is incorrect because it doesn't clearly address whether the officials' belief is reasonable. From my view, the answer stem already mentioned that "there were reasonable grounds." Could someone clarify this for me?
