The full question is this:

The correct option is B.
Some E.coli are harmless while some are pathogenic and can cause diseases such as diarrhea. The E.coli that cause diarrhea can be transmitted through contaminated food or water. Beef and dairy cattle are animal reserves of E.coli; they are found in the intestinal tracts of these animals and they cause illnesses in people who eat beef or take milk obtained from these cattle.
