Environmental Factors Impacting Personal Health: A Key Example

The correct answer is C: Access to clean water.

Access to clean water is a crucial factor that can significantly influence personal health. The availability of safe drinking water reduces the risk of waterborne diseases, such as diarrhea, cholera, and typhoid fever, which can have severe health consequences. These diseases are prevalent in areas where access to clean water is limited or nonexistent. By providing access to clean water, individuals can improve their overall health and well-being, preventing illnesses and promoting better hygiene practices.
