The correct answer would be:
b. Risky and dangerous
Unlike Tom's plan for freeing Jim in Mark Twain's novel "Adventures of Huckleberry Finn," Huck's plan is considered risky and dangerous. While Tom's plan is elaborate and filled with unnecessary complications inspired by adventure stories, Huck's plan is more straightforward and practical. Huck's approach involves a simpler and more direct method of helping Jim escape from slavery.
