The conference was held near Yalta in Crimea, Soviet Union, within the Livadia, Yusupov, and Vorontsov Palaces. The aim of the conference was to shape a postwar peace that represented not only a collective security order but also a plan to give self-determination to the liberated peoples of Europe.
Ok, so obviously, you can tell that A. is not even an answer since his name is Prince Henry which is an English name and the Islamic empire never really reached what is now present-day U.K...B. and D. are wrong because Catholicism was in Spain and the Pope was also in Spain. So your only correct answer is C.
