### **Quiz Questions on Body Weight and Nutrition**

**Question 7:**  
A weakness in using BMI to assess body weight is:
- A. BMI does not indicate the ideal weight for a given height
- B. BMI does not assess where fat is distributed on the body
- C. BMI does not account for differences in age

**Explanation:**  
Body Mass Index (BMI) is a widely used measure to categorize individuals based on body weight relative to height. However, this method does have limitations.
