Answer:
option C is correct.
Explanation:
Dirty hands is the correct answer because our hands are always touching everything and grabbing things as well..
for example: when we shake someones hand twice as many germs we already had on our hand transfers to us.
also when we grab food out of a bad or box we touch more than just the piece we intended to grab and we spread our germs to the food and slowly all of the food will be infected/mold
