The gastrointestinal tract is a warm, safe environment full of nutrients and is ideal for many types of microbes. Why would an organism capable of colonizing the intestine produce toxins that would lead to diarrhea, increasing the likelihood that it would be washed out of its habitat? A. Diarrhea increases the dissemination of the organism into the environment, where it can encounter new hosts.

B. Causing illness in the host makes it easier to get nutrients from the host's body.

C. Causing illness in the host decreases the likelihood that the host immune system will find or destroy the pathogen.

D. There is no advantage to the pathogen. Diarrhea is completely due to the immune system trying to remove the pathogen, not caused by actions of the pathogen.
