Final answer:
Time, weight, length, and other physical measures are best represented by ratio scales, which not only have a zero point but also permit ratio comparisons and magnitude differences. Therefore, the correct option is d.
Step-by-step explanation:
Time, weight, length, and other physical measures are best exemplified by ratio scales. A ratio scale is a level of measurement that not only has a natural zero point but also allows for the comparison of absolute magnitudes and the computation of ratios. For instance, weight can be measured in pounds or kilograms, which can be ordered, differences can be calculated, and the ratios are meaningful (e.g., one object can be twice as heavy as another).
