Answer:
The high-involvement hierarchy
Step-by-step explanation:
Roderick wants to evaluate several products before deciding which one to buy for his daughter, because he wants to buy the product that has an affective value, as there are several products that perform the same activities.
For this reason, we can conclude that Roderick's actions reflect the concept of high involvement hierarchy, which is a type of pre-purchase evaluation, where a product is chosen based on the attributes and the degree of affective involvement that the product passes to the client. This usually occurs with multiple products that perform the same function.
