I believe it's A.
The Muslims did control Jerusalem for a time, and I believe that they forced the Christians out of it.
Also the Crusaders did sack Constantinople when they were not allowed in by the government there.
I don't know what D is but I'll assume that it is true because I think A is false.
From what I know ethnocentrism means someone who thinks their culture is higher than another therefore I would go with A.
Answer: UN resolution on security
Explanation:
After the end of World War II, a UN institution was established because of the extent of the destruction that the war had brought. Many goals and objectives are set before the assembly of this. One of the UN's tasks is to maintain peace in the world. This institution was founded in 1945. If a war threat arises, the UN has several ways to respond.
In this context, Chapter 7 of the UN Charter provides several mechanisms for conflict prevention. If the council accepts the fact that the threat is real, they call on the party who caused the conflict to end the military offensive. If the warning is rejected, UN member states are ordered to sever bilateral and economic relations with the country. If the conflict continues, the UN may use military force.The adoption and implementation of the UN screw amendment require two-thirds of the votes of the UN General Assembly.The US, Russia, China, France, and the United Kingdom have the right to veto every decision.
