His superb skill at hunting enables him to outwit Zaroff.
On the ship, his curiosity leads him to fall overboard.
The entire conflict in the story revolves around Zaroff hunting Rainsford. Zaroff offers Rainsford a deal that if Zaroff doesn't catch Rainsford by midnight on the third day he'll let Rainsford leave the island. However, Rainsford may not tell anyone. Rainsford doesn't take this deal because he cannot morally agree to keeping Zaroff's hunting humans a secret. Rainsford must outwit Zaroff in order to stay alive. He is successful and even ends up sleeping in Zaroff's bed.
Option B is also correct. While on the ship Rainsford hears gunshots. Curious about where they came from and what is happening, he climbs onto the rail of the ship for a better view. He falls overboard while he's on the rail.
The last two are not correct. He does not gain any insight into animal feelings and his cleverness does not lead him to realize that Ivan must be killed.
