Answer: A. land-hungry politicians from the West and South.
The people who most supported the idea of war were a group of young Congressmen from the West and South known as the "War Hawks." These congressmen were particularly land-hungry, and their desire for war was driven by their expansionists interests. They wanted to add territories such as those of Canada and Florida to the territory of the United States, as well as to continue pushing the frontier West into indigenous lands. This group was particularly influential in Madison's decision to declare war to Great Britain.
