**Why Each Wrong Option is Incorrect:**

A. **Alcohol consumption**: While moderate alcohol intake may have some health benefits, excessive alcohol consumption has detrimental effects on various organs and can lead to alcohol-related disorders.

B. **Dietary supplements**: While dietary supplements may provide additional nutrients, relying solely on supplements to maintain health is not recommended as whole foods contain a more comprehensive range of nutrients and fibre.

C. **Sedentary lifestyle**: Engaging in minimal physical activity increases the risk of chronic diseases and negatively impacts overall health and wellbeing.

Aim for at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity aerobic exercise per week, along with muscle-strengthening activities on 2-3 days per week.

3. **Sleep and rest**: Adequate sleep and rest contribute to tissue repair, immune system function, and cognitive performance
