Verified step by step guidance

1. Step 1: Understand the concept of Body Mass Index (BMI). BMI is a measure of body fat based on an individual's weight and height. It is calculated using the formula: BMI = weight (kg) / height² (m²).
2. Step 2: Learn the classification ranges for BMI. According to the World Health Organization (WHO), BMI is categorized as follows: Underweight (<18.5), Normal weight (18.5–24.9), Overweight (25.0–29.9), and Obesity (≥30.0).
3. Step 3: Identify the range that corresponds to 'Normal weight' based on the classification. From the provided options, the range 18.5–24.9 matches the normal BMI category.
4. Step 4: Compare the other ranges provided in the question to the BMI classification. For example, 15.0–18.4 falls under 'Underweight,' 25.0–29.9 falls under 'Overweight,' and 30.0–34.9 falls under 'Obesity.'
5. Step 5: Conclude that the correct answer is the range 18.5–24.9, as it represents the normal BMI category for adults.
