C. increased the political power of citizens in Kenya.
Option C is the correct answer because the new constitution in Kenya, adopted in 2010, established three independent branches of the national government and granted several rights to the citizens, including the right to recall legislators, the right to be directly involved in making national policy, and the right to request that the legislature pursues issues important to the people. These provisions in the new constitution aim to increase the political power of citizens in Kenya, allowing them to have a more significant role in the governance and decision-making processes of the country.
