Well, since the prokaryotic organism dies if it is exposed to oxygen, as it cannot utilize the products of oxygen and thus uses fermentation, it would be an C. Obligate anaerobe.

Answer:

C. Obligate anaerobe

Explanation:

Anaerobic bacteria are most heterotrophic bacteria.

Obligate anaerobic bacteria are those that live under anaerobic conditions, in other words, in oxygen-free environments, because when in the presence of oxygen they are harmed and may even die.

In the case of these bacteria, the energy of organic compounds without oxygen is obtained through fermentation, which can be lactic or alcoholic, for example.
