Which of the following best distinguishes deltaproteobacteria from epsilonproteobacteria?
A. Deltaproteobacteria are most commonly found at anoxic-oxic interfaces while epsilonbacteria are most commonly found in anoxic environements.
B. Many epsilonbacteria oxidize sulfur compounds, which could be produced by a sulfur-reducing deltaproteobacterium.
C. A sulfate-reducing epsilonbacterium produces sulfite, which a deltaproteobacterium reduces further to hydrogen sulfide.
D. An epsilonbacterium reduces sulfur compounds whereas all deltaproteobacteria oxidize sulfur compounds.
