The passage tells us that NBS is true. But you'll notice, not CFV is a SUFFICIENT condition of NBS, not a necessary condition. So it is not the case that not CFV must be true, Thus (A) is correct, since we are looking for the one answer choice that COULD be FALSE.

NBS ==> DACA ==> SMI. So since we know NBS is true, SMI must be true. Thus (C) is incorrect.
