If You Wanted to Provide the Most Data for an Audience

If you wanted to provide the most data for an audience about the species composition of a community and how it changes over time,which of the following would you use and why?

A) Use species richness because it shows the audience one how many species are present in a community.
B) Use a diversity index because it shows the audience the species present and how common or rare those species are in that community.
C) Use niche breadth because it shows the audience how many niches are in use in a community and the number of species using them.
D) Use a rank-abundance diagram because it shows the audience about relative abundances, changes to relative abundances, number of species, and how the number of species changes over time.
