e?

  #3

I go with c because it has 3 types A,B, and C.


  #4

Its E! Polio.
It has 3 serotypes which do NOT change significantly from year to year or within person.

Its no C because there are many serotypes and it changes from year to year, and they are nowhere near eradicating it. (people have to get flu shots every year because there are so many strains and they are rapidly changing) ---Influenza is responsible for epidemics and pandemics because of the genitic drift and genetic shift.
