select the best answer from the choices provided.

a
b
c
d

The answer below is correct.. (B) but heres why First of all to eliminate our C answer im just going to say that cystic fibrosis is untreatable.. (there is not a cure developed yet) so just cross that one out:)
And A is also incorrect because many many many many man people have lived far beyond their  teenage years with cystic fibrosis So lets cross out A:)
and finally D occurs most frequently in people of Asian descent. Let me just say No because this is a gene passed on from both of your parents. So this could be from any type of race (not just Asian) anyways! 
so our loyal and true answer here is B! because yes it does make it difficult to breath. 
SO ANSWER? = B
if this wasnt confusing and you understood it and it helped you then please dont forget to
MARK ME BRAINLIEST! :D
