The waist-to-hip ratio is a significant health measurement used to assess the distribution of body fat. The formula for calculating this ratio focuses specifically on the relationship between the circumference of the waist and that of the hips.

The correct approach involves taking the circumference measurement of the waist and dividing it by the hip circumference, both measured in the same unit. Option B accurately captures this method by specifying both measurements in inches. This consistency in units is crucial because it ensures the ratio reflects the correct relationship between the two measurements.

Using consistent units like inches or centimeters is important in physical assessments to maintain accuracy and convenience. Additionally, while other methods might suggest using different operations, they do not adhere to the fundamental principle of the waist-to-hip ratio calculation, which is strictly a division to yield a proportionate value.
