This is an example of man vs man. This is because hunter Rainsford attemps to outrun and outwit the sadistic Zaroff, who hunts humans for sport. This is a conflict between two people so it is man vs man.
This would be an example of man vs nature. I say this because Rainsford is at the verge of his death. He then uses the jungle and his surroundings to his advantage to keep him safe.
Man vs Self is presented in this strip. This is because Rainsford struggles with his own fear. He also struggles with how best to win this “most dangerous game.”
