Answer:
The correct answer is D. is a facultative anaerobe
Explanation:
A facultative anaerobe is the organisms that can live in the absence of oxygen but prefer to utilize the oxygen when oxygen is present in the environment.  
An anaerobic organism requires more amount of energy sources like carbohydrates because they use the fermentation process to make energy and this process results in the formation of less energy than aerobic respiration.  
All the bacteria of family Enterobacteriaceae that live in the intestine are facultative anaerobes. Therefore facultative anaerobe can thrive in both the presence and absence of oxygen so the correct answer is D. is a facultative anaerobe.

Peristalsis is the name for the waves of contractions that propel substance s along a tract. It is a series of wave-like contractions that moves food to different processing stations in the gastrointestinal tract and starts in the esophagus when the boluses of food are swallowed. The wave motion is produced by the longitudinal smooth muscles that line up the esophagus, stomach, small intestines and the colon and is triggered by presence of food.
