Biodiversity describes the variety of life across multiple levels, including genetic variation within populations, the diversity of species in a community, and the range of ecosystems within an area. The prompt lists genetic variation within a population, the variety of species in a community, and the variety of communities in an ecosystem—all of which collectively define biodiversity. Other terms describe narrower ideas: a population is the group of individuals of one species in a location, a species is a group that can interbreed, and an adaptive trait is a heritable characteristic of individuals—not the overall variety across life forms and habitats. So biodiversity best fits because it encompasses all those different kinds of variation.
