D)ranges
E)interquartile ranges

Comparing the coefficients of variation (CV) from the two samples would be the most appropriate way as it is a standardized measure of dispersion that accounts for the different measurement scales of the two variables. The CV is calculated as the ratio of the standard deviation to the mean, expressed as a percentage. By comparing the CVs, we can see which variable has relatively more variation compared to its mean in each sample and can compare the relative variation between the two variables across the two samples.
