 B. Cartography

Explanation:   Cartography is the study of mapmaking defined, among others, by the International Cartographic Association. This discipline deals with the study, conception and production of maps. The name of the cartography comes from the Greek-Latin word "charta", which means a leaf of paper, and the Greek word "graphein", which means to draw or write. Cartography implies a whole mapping process, from studying a mapped relief to a presentation, that is, drawing on a map.
