The respiration pathway that this species of bacteria is most likely using is D. anaerobic respiration.

Since it says in the question that it grows in an oxygen-free environment, meaning that it doesn't need oxygen, anaerobic respiration should be the correct answer. Aerobic means using air, whereas anaerobic is the opposite.
