Answer: B. Instinct and experience
Explanation:
This is based on the novel, "Call of the Wild" by Jack London. We follow the story of Bucky which is a dog that was stolen from it's relative life of comfort and sold. Bucky ends up pulling sleds in Alaska and had to become more primitive in order to survive the harsh environment.
Bucky and some other dogs are sold to some masters named Mercedes, Charles and Hal. They wanted to travel and tried to make Bucky the lead dog but he refused because he had instinct and experience which told him that troubles were up ahead. He was right as the trip claimed the lives of most of the dogs.
