Microbes can be challenging to study because they often grow in complex communities and it may be difficult to separate the various species from one another to study individually.Which of the following laboratory "tools" or techniques may be of the the most help with separating out different species from complex mixtures?
A)use of transmission electron microscopy
B)use of enriched agar for culture
C)use of selective agars for culture
D)use of light microscopy

Selective agars are designed to promote the growth of specific microbial species while inhibiting the growth of others, making them useful for separating out different species from complex mixtures. Enriched agar may help to promote growth of a particular microbial species, but it may not always be effective at separating out different species. Transmission electron microscopy and light microscopy are imaging techniques that can help visualize individual cells but do not aid in physically separating them.
