B Correct answer
Explanation

The unabsorbed and undigested food then passes from the ileum into the cecum, the beginning of the large intestine. This food residue is full of bacteria. After absorption the remaining undigested matter is squeezed into a bundle called feces. About 30% of the weight of feces is bacteria. These bacteria are good bacteria and billions of them live in our colon all the time.
