Answer: The knight has the highest social status.
Step-by-step explanation:
The Knight is a character from The Canterbury Tales, Geoffrey Chaucer's story collection. He is the first pilgrim to appear in the General Prologue, and is generally a member of the very high social class of the nobility.
Although Chaucer describes twenty-nine pilgrimages in total, it is the knight that is described as generous, courageous, chivalrous, and respectful, and therefore fits into the upper class.
