The correct answer is D. The 31 March Incident refers to the dissatisfaction of non-Muslim subjects from the Ottoman sultan. This event occurred on 31 March 1909, when a group of non-Muslim students at the Ottoman War College in Istanbul protested against the government's education policies. The incident sparked a larger protest movement among non-Muslims in the empire, who were dissatisfied with their treatment and sought greater rights and representation. This event is considered a significant event in the history of the Ottoman Empire and contributed to the growing tensions between the government and non-Muslim subjects in the empire.
