Answer:
The most appropriate answer would be D. Certain vitamins might not be synthesized and foods might not break down as well.
Gut flora in humans play many important functions such as:
- They inhibit the pathogenic microorganisms by competing with them for space and nutrients.
- They help in digesting few polysaccharides that humans can not digest by themselves. For example, starch, fiber etc.
- They help in absorbing lactose in lactose-intolerant patients.
- They help in synthesizing vitamins specially biotin and folate. In addition, they help in absorption of various dietary minerals such as calcium, magnesium, iron etc.
- They help in digesting xenobiotics. etc
