The correct answer is B) arrest him due to the court’s limited authority.
Omar al-Bashir is the president of Sudan and the first head of state ever indicted by the International Criminal Court for crimes against humanity, which he committed during the war in Darfur. He is alleged to have directly and systematically planned a genocide, persecution, and pillage of thousands of civilians of different ethnic groups.
In 2009, the International Criminal Court (ICC) indicted al-Bashir for these crimes and, although the ICC's indictments have a binding effect, it was not able to arrest him due to the fact that the execution of the ICC's orders are subjected to the good will of the states. Albeit the ICC has jurisdiction over crimes committed in Sudan due to a resolution of the UN Security Council, Sudan refused to deliver its president to the Court. This is because the ICC has a limited authority which depends on the will of the states.
