Some bacteria of the same species and genotype can reduce sulfur anaerobically for energy, depending on the environment. This an example of...

A)growth and response

B)genotype mutation

C)phenotypic plasticity

D)inclusive fitness

C) phenotypic plasticity

Explanation:

Organisms might adjust their morphology and physiology to a better performance in environmental heterogeneity.

Generalists species might present a higher magnitude of phenotypic plasticity than specialist species.

These bacteria are notoriously adaptable and might be found in many different environments (terrestrial and/or aquatics) where there is no oxygen due to aerobic decomposition of the organic matter.  

They can be found in anoxic sulfuric environments. In the soil, in estuaries mud, in freshwater, in sewage systems, salty waters, thermal water, sulfur deposits, in oil and gas wells, and even in animals and insects intestine.
