High Species Diversity, Considered a Positive Attribute of a Community

High species diversity, considered a positive attribute of a community, is measured by both species richness and species evenness.How would higher species evenness likely act as a positive factor in the community?

A) There would be fewer rare species; thus, there would be more individuals of each species, which could lower extinction risk.
B) There would be more rare species; thus, more species would remain in the community and fewer extinctions would occur.
C) There would be more total species present; thus, the food web would have more links.
D) There would be fewer total species present but more similar numbers of each, thus making cross-species reproduction easier.
E) There would be an overall lower species diversity, because species richness is more important in diversity than species evenness.
