A. a poor farmer in Kansas
Populist movements usually target lower classes (or whatever group of people who are very numerous in the society), and promise improvement of their status, with ideas which are impossible to implement.
The Populist Party most likely represented a poor farmer in Kansas, as the movement was primarily focused on advocating for the rights and interests of farmers and working-class citizens against powerful economic elites. The other options, including bankers and wealthy landowners, were more representative of the groups the Populists opposed. Therefore, option A is the correct choice.
