The correct answer is: b) Village heads.
A Kazi is a village head in Bhutan. The title of Kazi was sometimes granted by the Chogyal to individuals who held positions resembling village heads. Kazis were responsible for collecting taxes, settling disputes, and maintaining law and order in their villages. They were also responsible for representing their villages to the Chogyal and the central government.
The other options are incorrect. Feudal lords were not appointed by the Chogyal, but rather inherited their positions. Royal priests were appointed by the Chogyal to serve in the Buddhist monasteries. Military commanders were appointed by the Chogyal to lead the Bhutanese army.
