Some scientists are proposing that if the H5N1 avian flu strain does begin to spread from person to person, antivirals are then sprayed over the affected geographical areas much as pesticides are sprayed over fields; this unprecedented strategy could slow the spread of the disease and “buy time” for individuals to be properly vaccinated.

A) that if the H5N1 avian flu strain does begin to spread from person to person, antivirals are then sprayed over the affected geographical areas

B) that if the H5N1 avian flu strain does begin to spread from person to person, antivirals be sprayed over the affected geographical areas

C) that antivirals should be sprayed over the affected geographical areas, if the H5N1 avian flu strain does begin to spread from person to person,

D) if the H5N1 avian flu strain does begin to spread from person to person, antivirals should be sprayed over the affected geographical areas

E) spraying antivirals over the affected geographical areas, if the H5N1 avian flu strain does begin to spread from person to person,
