The correct answer is mutualistic. This kind of relationship is a "give-and-take" relationship between the organisms wherein both organisms benefit from each other. In this case, the human gives the E. coli its habitat along with its food and nutrients. The E. coli on the other hand gives the human its normal gastrointestinal flora as well as providing vitamin K to ensure clotting mechanisms are intact.
