Answer:
d. retail positioning matrix
Step-by-step explanation:
In the example, it is noted that Boston Market has added value to its original restaurant format (with pickup, delivery...) on the one hand. On the other hand, they broadened the product line with the grocery foods. The two factors imply the axes of the retail positioning matrix.
The retail life cycle is an often confused topic that is similar to the product life cycle (which is related to products and services exclusively) conceptually. It consists of the following phases: innovation, growth, maturity and decline. Although this example can be correlated to the innovation phase of the retail life cycle, we cannot pinpoint the Boston Market's place on the retail life cycle curve, as we do not have info about its competitors, market share and other external info. Therefore, we cannot detect whether the company is in its up or down phase.
The wheel of retailing is an irrelevant concept, which refers to the tendency that most retailers enter a market in an extremely competitive manner (low cost, for example) and then becomes more exclusive (high cost, better reputation...).
