Option D, Personal habits, such as hand washing, have greatly reduced contamination from bacteria.
Explanation:
Diseases like typhoid and cholera became pandemic a century ago because people at that time were not aware of the general hygiene and its impact on killing microbes.
Majority of human diseases are caused by either bacteria or virus only when they ingest into the internal body system. The entry of microbes can be restricted by adopting healthy hygiene habits such as washing hands regularly with disinfectants, washing vegetable properly before cooking etc.
Such habits break the chain of contamination and hence prevent the disease from spreading.
