C) to create new variables that are composites of several other variables
D) none of the above

Scale transformation would be useful in comparing variables that have different scales or units of measurement, such as the seven-point semantic differential scale, continuous rating scale, and five-point Likert scale in option A. It involves rescaling the data so that they are on a similar metric, usually with a minimum of 0 and maximum of 1 or -1 to +1. Option B discusses weighting the sample, which is a different technique. Option C refers to creating composite variables, which would involve combining different variables in a meaningful way to create a new measure.
