Suppose you are a researcher in an influenza lab and your team has uncovered four strains that have evolved changes from last year's influenza virus.Strain A has evolved four changes in its surface proteins and three changes in its interior proteins.Strain B has evolved two changes in its surface proteins and seven changes in its interior proteins.Strain C has evolved six changes in its surface proteins and none in its interior proteins.Strain D has evolved only a single change in its surface proteins and none in its interior proteins.Assuming that all other factors are equal,which strain is most likely to be infectious?
A) Strain A
B) Strain B
C) Strain C
D) Strain D
E) All of the strains are equally likely to be infectious.
