Answer 13

I started to write, but I don't think I had the right answer.
My most probable (and politically correct) answer is C, which actually worked for me. However, there is also the factor that colds are also spread by fine air droplets (aerosol effect), for which hand washing and avoiding touching eyes and nose would not help.
B. is definitely out because most colds and flu are caused by viruses, against which antibiotics don't help.
A and D could be contributing factors, but cannot be the sole reason.
So there, make your best pick.

P.S. Probably this is a math forum, not too many people are experts in the field, as you can see. Sincerely apologize on behalf of Openstudy!
