Answer:

I think the answer is A all of the above

Sorry if im wrong.

I did some research

16s gene It is widely present in all bacterial species.(B)

16s gene

Because it contains both highly conserved regions for primer design and hypervariable regions to identify phylogenetic characteristics of microorganisms, the 16S rRNA gene sequence became the most widely used marker gene for profiling bacterial communities (C)
