Answer:
c. he made a truce concerning jerusalem.
Explanation:
Although Richard I didn`t retake Jerusalem from the Muslim, he made a truce with the Sultan Saladin. After a bloody and struggled battle, both leaders decided to make a deal: Christians maintained what they had achieved in Palestine and obtained the right to pilgrimage (provided they were unarmed) to Jerusalem (which would remain in Muslim hands). This truce would remain until the uprising of the 4th Crusade.
