For this question my answer was E- because if there are more people harbouring H pylori than M tuberculosis, and since H pylori allegedly strengthens immune system, then it strengthens the fact of it being commensal, and thus beneficial. Thus weakening the argument.
Can someone explain why the answer is C? Doesnâ€™t this answer strengthen the argument?
