Hi there :)
Your answer is B. Hygiene. Its important to keep ourselves clean because if not, then dirt will start to build up in our skin from 2 days or more with washing and then bacteria will start to build up on your teeth from not brushing. Taking showers keep our body clean and helps wash of the bacteria and brushing out teeth is important because when you eat and the let food sit on your teeth, it builds up tartar which come from food being build up so basically I think its like a bacteria hat sits on teeth until it's cleaned and if no one wants that to happen, then that's why we brush our teeth two-times a day. Then it's so important to wash because sometimes when you go days without taking a shower or bath, it can lead up to built up dirt, and make us smell a certain way. So its important the both Women and Men to keep up with their hygiene.
I hope that helps :)
Have A Good Day :)
