Final answer:
Option (c), BMI is calculated using the formula [weight (lb) x 703] ÷ height(in)², and it helps in classifying individuals as underweight, normal weight, overweight, or obese. It's a tool used for assessing body fatness in populations but has limitations for individual assessments.
Step-by-step explanation:
The subject is calculating Body Mass Index (BMI), which is a numerical computation that involves the weight and height of an individual.
The correct formula to calculate BMI is given by the equation BMI = [weight (lb) × 703] ÷ height(in)². BMI categories include underweight (BMI below 18), normal weight (BMI 18-24.9), overweight (BMI 25-29.9), and obese (BMI over 30).
According to the Centers for Disease Control and Prevention (CDC), BMI is a useful indicator of healthy body weight, but it has limitations since it does not account for muscle mass in individuals like athletes.
