Step 1: Understanding Body Mass Index (BMI) BMI is a metric used to classify individuals based on their weight relative to their height. It is computed using the formula: \[\text{BMI} = \frac{\text{Weight (kg)}}{[\text{Height (m)}]^2}\] Step 2: WHO classification of obesity According to the World Health Organization (WHO), the BMI categories are as follows: - Underweight: BMI < 18.5 - Normal weight: BMI 18.5–24.9 - Overweight (Pre-obese): BMI 25.0–29.9 - Obesity Grade I: BMI 30.0–34.9 - Obesity Grade II: BMI 35.0–39.9 - Obesity Grade III (Severe or Morbid Obesity): BMI >= 40.0
Step 3: Identifying Grade II Obesity Grade II obesity falls within the BMI range of 35.0 to 39.9, which aligns with Option (C).
Step 4: Final Answer Therefore, the correct answer is Option (C): 35.0–39.9.
