• B. Providing vitamins to host
• C. Anaerobic respiration

Answer 1

The correct option is D Aerobic respiration

Intestinal symbiosis initiates the process of digestion and helps to receive nutrition by degrading the polysaccharides in the host. one of the bacteria present in small intestine is Escherichia coli bacteria. It feeds on the waste food in the host. It provides nutrition and vitamins to the host. It degrades the food by breakdown of complex food by the process of anaerobic respiration. So, aerobic respiration does not take place.

So, option D is the correct answer.
