Final answer:
The positioning strategy that uses price to create a perception of quality is the Quality and price strategy, where a higher price is perceived as an indicator of higher quality, especially when the consumer has imperfect information.
Step-by-step explanation:
The positioning strategy that creates the perception of quality through price is Quality and price. When a company uses price as a signal of quality, it operates under the assumption that customers will believe that a higher price indicates a higher-quality product. This is particularly true in situations where the buyer has imperfect information about the actual quality of the product, such as with gemstones, legal services, or luxury items. Thus, when price is combined with imperfect information, it can be a significant factor in product differentiation, influencing consumer perception.
