The major purpose of hygiene is to:

  1. control population growth

  2. promote disease

  3. teach barber-styling

  4. preserve health

The correct answer is: preserve health

Hygiene may often involve controlling bacterial or viral growth, but its primary goal is to preserve and promote health, not control population growth. Teaching barber-styling is not a main purpose of hygiene, as it involves more than just hair and grooming practices. Similarly, the purpose of hygiene is not to promote disease, but to prevent and control it. Overall, D is the most accurate answer as it encompasses the main purpose of hygiene.
