What Did the Comparative Study on Chytridiomycosis Teach Scientists Studying

What did the comparative study on chytridiomycosis teach scientists studying white-nose syndrome in bats?

A) It was probably not a fungal infection affecting the bats and scientists needed to look elsewhere for a cause.
B) Chytridiomycosis affected only certain amphibians,so the comparative study could not teach the scientists anything useful.
C) A novel fungal infection could spread to colonies and cause dramatic population crashes,as seen in the comparative study.
D) Humans were responsible for the spread of chytridiomycosis,but not white-nose syndrome.
E) White-nose syndrome affects bats but does not cause death in organisms like chytridiomycosis does in amphibians.
