What is an effect of chaucer's decision to use a pilgrimage as the central premise for the canterbury tales?

In sparknotes, it says that "The travelers were a diverse group". I believe because of this, Chaucer's main purpose was to have a diverse group of characters in the story plot. It also mentions in sparknotes that "His intention to describe each pilgrim as he or she seemed to him is also important, for it emphasizes that his descriptions are not only subject to his memory but are also shaped by his individual perceptions and opinions regarding each of the characters." I believe that the answer is: C. It provides Chaucer with an opportunity to write about characters that represent a wide range of social classes.
