Who Has Good Personal Hygiene?

This is from my Mobile Food Vendor Food Protection Course workbook. After lots of learning and lessons, I had gained enough knowledge to choose the correct answer, B. However, B is not a hygiene ideal; her fingernails, for instance, are far too long. And she appears to be wearing jewelry, which is not appropriate--maybe one of her earrings could fall into a hotel pan full of sauerkraut.
