Question

bmi takes into account someones height, weight, and ____. ethnicity age activity level

Explanation:

BMI (Body Mass Index) is calculated using the formula \( BMI=\frac{weight(kg)}{height(m)^2} \) for adults, but for children and teens, age is also a factor as BMI percentiles are used which depend on age - and - sex - specific growth charts. Ethnicity and activity level are not part of the standard BMI calculation. So the correct factor here is age.

Answer:

B. age
