Explanation / Answer

The human microbiome includes all the microorganisms that reside on or within human tissues or body fluids. There are roughly 10 times as many microbial cells than human cells in/on an average body. The same species of bacteria are not found in nearly all bodily environments. The relative abundance of bacterial species does not remain constant throughout a human's lifetime. The microbial composition is dictated by both the host environment and genetic factors. The microbial biomass is less than human biomass. So, the correct option is option D, there are roughly 10 times as many microbial cells than human cells in/on an average body.
