The correct answer and the quote that best illustrates the story's that following tradition blindly can be hazarous is C. "Althought the villagers had forgotten the ritual and lost the original black box, they still remember to use stones."
The villagers do not know about the tradition's origin, yet they are devoted to its preservation and they have turned ritual murder into a village tradition. They do not even question why they do it or if it is wrong to kill someone. The fact that the lottery is a tradition is justification enought to kill people.
