Final answer:
Research studies on alcohol use have shown that moderate use of alcohol may increase longevity (option C).
Step-by-step explanation:
Moderate alcohol use may increase longevity, but excessive consumption causes major health problems. The effects of alcohol vary based on the individual's BAC. Overuse, especially among youth, leads to significant health and societal issues.
This is because people who drink a moderate amount of alcohol regularly have been statistically linked to living longer than those who abstain. However, it is essential to recognize that excessive consumption of alcohol can lead to numerous health issues, including impaired coordination and judgment, an increase in some cancer types, and physiological disorders like cirrhosis of the liver. Additionally, heavy drinking is a significant factor contributing to road accidents and other undesirable outcomes like family disruption and job loss.
Thus, the correct option is C.
