Final answer:
In Geoffrey Chaucer's The Canterbury Tales, it is The Parson who never stopped for rain or thunder, demonstrating his commitment to his parishioners.
Step-by-step explanation:
The character from The Canterbury Tales who "never stopped for rain or even for thunder" is c. The Parson. In Geoffrey Chaucer's collection of stories, the Parson is described as a devoted and diligent churchman who is dedicated to his parishioners and to the duties of his office. Regardless of the weather, he would visit the farthest members of his parish, exemplifying his commitment and compassion. The Parson's travels in adverse weather conditions highlight his sense of duty and moral integrity, in contrast to some of the more morally dubious characters in The Canterbury Tales.
