Who buys Buck from Perrault and Francois?

The correct answer is that Buck is purchased by the Scot. This choice accurately reflects a critical moment in the story when Buck is sold to this new character, who plays a significant role in Buck's journey into the brutal realities of life in the Yukon. The Scot is depicted as part of the expanding gold rush era, where dogs were in high demand for sledding, emphasizing the harsh conditions and human motivations driving the narrative.

To provide context, Judge Miller, who is Buck's original owner, represents Buck's previous life of comfort and stability before his transformation. Hal, on the other hand, is an abusive character who comes into play later, signifying the dangers Buck faces in his new environment. The Yee-hats are a group of Indigenous people Buck encounters, but they don't purchase him; rather, they are involved in a significant conflict later in the story. Thus, understanding why Buck is bought by the Scot is integral to grasping his transition from domestication to the wild, reflecting the overarching theme of survival in "The Call of the Wild."
