We should wash our hands regularly to reduce the risk of contracting communicable diseases because washing hands can reduce the amount of microbes on our hand by more than 50%.  

So after doing any work in which our hands touches many surface which are not clean we should wash our hands with soap properly so that we do not get ill by communicable disease. So the right answer is C.
