Final answer:
The company with the highest rating on a given measure has an implied competitive edge that reflects the difference between its weighted rating and rivals' weighted ratings.
Step-by-step explanation:
The company with the highest rating on a given measure has an implied competitive edge on that specific measure, and this reflects the difference between its weighted rating and rivals' weighted ratings. The size of its edge provides the company with an overall net competitive score that is reduced by the weighted measure. Therefore, option c) reflecting the difference between its weighted rating and rivals' weighted ratings, is the correct answer.
