The correct option is D
The crusaders were Christian soldiers, mainly from Western Europe, who participated in some of the crusades in the Middle Ages. The name derives from the custom of sewing or painting a cross on their clothes (hence the expression "take the cross", which indicated those people who left to participate in the crusades). The term "crusader" did not begin to be widely used until the fifteenth century, since previously these were considered as armed pilgrims.
The monarchs had used their wealth to fund expeditions for explorers. The explorers would’ve worked for them in exchange for expedition fund or to at least acquire a better chance at being funded.
