Identify the B.M.I. range of Grade Il obesity:

The correct option is 35.0-39.9.

Body Mass Index (BMI) is a standard value used to classify nutritional status, overweight, and obesity in adults. According to the World Health Organization (WHO) classification, obesity is divided into three distinct grades or classes based on the severity of the BMI range:

• Underweight: BMI less than 18.5 kg/m²
• Normal weight: BMI between 18.5 and 24.9 kg/m²
• Overweight (Pre-obese): BMI between 25.0 and 29.9 kg/m²

For individuals classified as obese (BMI ≥ 30.0 kg/m²), the categories are further subdivided as follows:

• Grade I Obesity (Class 1 - Moderate): BMI range of 30.0 to 34.9 kg/m²
• Grade II Obesity (Class 2 - Severe): BMI range of 35.0 to 39.9 kg/m²
• Grade III Obesity (Class 3 - Very severe/Morbid): BMI of 40.0 kg/m² or higher

Therefore, the BMI range corresponding specifically to Grade II obesity is 35.0-39.9.
