B) The Europeans discovered many new goods
A) is only true for the first Crusade. After that, the Crusades mainly failed at their tasks, and so A is out of the question
C) is false, because the Suljuk Turks continued to hold the land until WW1, when Jerusalem was finally freed by French and British soldiers
D) is kinda false, because it is the Europeans that discovered many new inventions and books
hope this helps
