Answer:
It shows readers that Rainsford is smart and has skills. He has a chance of survival in the "game" against Zaroff.
Step-by-step explanation:
Richard Connell's short story "The Most Dangerous Game," tells the story of how an experienced hunter Sanger Rainsford became the hunted in a grim-twist of fate. The story deals with the themes of hunter-hunted relationships, social Darwinism, civilization, and murder.
In the given excerpt, Sanger Rainsford is already hunted by Colonel Zaroof, in an attempt to see whether he can achieve his freedom by escaping the hunter for three days. With that in mind, he decided to leave a "trail to follow" which will be confusing (or so he thought). His idea was to deceive the Colonel by providing some clues which will be all a ruse. This plan shows the readers that Rainsford is smart and has skills that can provide a chance to survive and win the "game" against Colonel Zaroff.
Thus, the correct answer is the third option.
