The Advantage of Using a Helical Instead of an Icosahedral

The advantage of using a helical instead of an icosahedral nucleocapsid to package a ssRNA genome is…..

A) it is more efficient to envelope a helical nucleocapsid than an icosahedral capsid.
B) it is easier to produce a helical nucleocapsid than an icosahedral capsid.
C) it better protects the genome from degradation inside the cell.
D) it requires a smaller protein to build than an icosahedral capsid.
E) it requires fewer copies of the nucleocapsid protein than an icosahedral capsid.
