Who was the famous Muslim leader during the Crusades known for his chivalry?

Saladin is recognized as the famous Muslim leader during the Crusades known for his chivalry due to his honorable conduct in warfare and his efforts to treat defeated enemies with respect. He played a crucial role in the Third Crusade, particularly noted for his victory at the Battle of Hattin in 1187, where he reclaimed Jerusalem from the Crusaders.

His approach to leadership and battle was characterized by a sense of honor and mercy, which earned him respect not only among his own followers but also from his adversaries. For instance, after the capture of Jerusalem, he allowed many of the Christian inhabitants to leave the city peacefully rather than slaughtering them or enslaving them, which contrasted sharply with the typical behaviors attributed to leaders of that era. This sense of chivalry is a significant aspect of why Saladin is remembered positively in both Arab and Western historical narratives.

Other figures mentioned in the options, while notable in their own right, do not match Saladin's combination of military prowess and humane treatment of opponents during the Crusades, which is what marks him as a chivalrous leader in that context.
