Final Answer :
D
Explanation :
Ratio scale is the most appropriate choice as it allows for meaningful comparisons of the differences in numeric values, such as height and weight, between groups. The ratio scale has a true zero point, which allows for the calculation of ratios such as body mass index or weight-to-height ratios. Nominal and ordinal scales do not allow for meaningful numeric comparisons, and interval scales do not have true zero points.
